</beans>
(二)在一的基础上集成spring 4.0.3 并整合JPA以及spring的单元测试
1)加上sping的依赖包,并在base模块进行引用。
<!-- spring包依赖-->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-core</artifactId>
<version>${spring.version}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>

<version>${spring.version}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-orm</artifactId>
<version>${spring.version}</version>
</dependency>
2)创建spring_base.xml,在spring配置文件中整合jpa
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"

<!-- 1
1)开启注解自动配置组件的自动扫描 (@Component是所有受Spring管理组件的通用形式)
@Repository、@Service和 @Controller则是@Component的细化,
用来表示更具体的用例(例如,分别对应了持久化层、服务层和表现层)
2)把use-default-filters属性設為false,意即在base-package所有被宣告為@Component和@Configuration等target Class
不予註冊為bean,由filter子標籤代勞。
Use-dafault-filters=”false”的情况下: <context:exclude-filter>指定的不扫描,
<context:include-filter>指定的扫描
-->
<context:component-scan base-package="org.smd" use-default-filters="true">
<!-- 只扫描Repository标注的类 -->
<!-- <context:include-filter type="annotation" expression="org.springframework.stereotype.Service" />
<context:include-filter type="annotation" expression="org.springframework.stereotype.Repository" /> -->
</context:component-scan>
<!--2配置数据源 -->
<bean id="dataSource"destroy-method="close">
<property name="driverClassName" value="${jdbc.driverClassName}" />
<property name="url" value="${jdbc.url}" />
<property name="username" value="${jdbc.username}" />
<property name="password" value="${jdbc.password}" />
<!-- 配置连接池的初始值 -->
<property name="initialSize" value="${initialSize}" />
<!-- 连接池的最大值 -->
<!-- <property name="maxActive" value="500"/> -->
<!-- 最大空闲时,当经过一个高峰之后,连接池可以将一些用不到的连接释放,一直减少到maxIdle为止 -->
<!-- <property name="maxIdle" value="2"/> -->
<!-- 当最小空闲时,当连接少于minIdle时会自动去申请一些连接 -->
<property name="minIdle" value="${minIdle}" />
<property name="maxActive" value="${maxActive}" />
<property name="maxIdle" value="${maxIdle}" />
<property name="maxWait" value="${maxWait}" />
</bean>
<context:property-placeholder location="classpath:jdbc.properties" />
<!--3 Spring整合jpa -->
<bean id="entityManagerFactory">
<property name="dataSource" ref="dataSource" />
<property name="persistenceXmlLocation" value="classpath:META-INF/persistence.xml" />
<property name="loadTimeWeaver">
<bean/>
</property>
</bean>
<!--4 事务管理器 -->
<bean id="transactionManager">
<property name="entityManagerFactory" ref="entityManagerFactory"/>
</bean>
<!--5 采用注释的方式管理事务-->
<tx:annotation-driven transaction-manager="transactionManager"/>
</beans>
3)在base模块创建 dao包,service等包,因为现在是集成阶段,具体搭建,等整合结束,再接着搭建
4)创建操作POJO类 的 productType的服务类ProductServiceImpl
public interface IProductService extends ICommonService {
/*****
* 保存productType
* @param productType
*/
public abstract void saveProductType(ProductType productType);
}
@Service
@Transactional
public class ProductServiceImpl implements IProductService {
@PersistenceContext
EntityManager entityManager;
/* (non-Javadoc)
* @see org.smd.base.service.IProductService#saveProductType(org.smd.base.model.ProductType)
*/
public void saveProductType(ProductType productType){
entityManager.persist(productType);
}
}
import org.junit.Test;
import org.junit.runner.RunWith;
import org.smd.base.model.ProductType;
import org.smd.base.service.IProductService;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("/spring_base.xml")
public class ProductTypeSpringTest {
@Inject
IProductService productService;
@Test
public void Test01(){
ProductType productType=new ProductType();
productType.setName("aa");
productService.saveProductType(productType);
}
}
运行单元测试,spring整合jpa,成功

JAVA springboot微服务b2b2c电子商务系统(四)SpringBoot 整合JPA
JPA全称Java Persistence API.JPA通过JDK 5.0注解或XML描述对象-关系表的映射关系,并将运行期的实体对象持久化到数据库中。
JPA 的目标之一是制定一个可以由很多供应商实现的API,并且开发人员可以编码来实现该API,而不是使用私有供应商特有的API。
JPA是需要Provider来实现其功能的,Hibernate就是JPA Provider中很强的一个,应该说无人能出其右。从功能上来说,JPA就是Hibernate功能的一个子集。
添加相关依赖
添加spring-boot-starter-jdbc依赖:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa
</artifactId>
</dependency>
添加mysql连接类和连接池类:
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<scope>runtime</scope>
</dependency>
配置数据源,在application.properties文件配置:
spring:
datasource:
driver-class-name: com.mysql.jdbc.Driver
url: jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf8&characterSetResults=utf8
username: root
password: 123456
jpa:
hibernate:
ddl-auto: update # 第一次简表create 后面用update
show-sql: true
注意,如果通过jpa在数据库中建表,将jpa.hibernate,ddl-auto改为create,建完表之后,要改为update,要不然每次重启工程会删除表并新建。
创建实体类
通过@Entity 表明是一个映射的实体类, @Id表明id, @GeneratedValue 字段自动生成
@Entity
public class Account {
@Id
@GeneratedValue
private int id ;
private String name ;
private double money;
... 省略getter setter
}
Dao层
数据访问层,通过编写一个继承自 JpaRepository 的接口就能完成数据访问,其中包含了几本的单表查询的方法,非常的方便。值得注意的是,这个Account 对象名,而不是具体的表名,另外Interger是主键的类型,一般为Integer或者Long
public interface AccountDao extends JpaRepository<Account,Integer> {
}

Spring Boot整合JPA使用多个数据源的方法步骤
这篇文章主要给大家介绍了关于Spring Boot整合JPA使用多个数据源的方法步骤,文中通过示例代码介绍的非常详细,对大家学习或者使用Spring Boot具有一定的参考学习价值,需要的朋友们下面来一起学习学习吧
介绍
JPA(Java Persistence API)Java 持久化 API,是 Java 持久化的标准规范,Hibernate 是持久化规范的技术实现,而 Spring Data JPA 是在 Hibernate 基础上封装的一款框架。
第一次使用 Spring JPA 的时候,感觉这东西简直就是神器,几乎不需要写什么关于数据库访问的代码一个基本的 CURD 的功能就出来了。在这篇文章中,我们将介绍 Spring Boot 整合 JPA 使用多个数据源的方法。
开发环境:
Spring Boot 2.0.5
Spring Data JPA 2.0.5
MysqL 5.6
JDK 8
IDEA 2018.3
Windows 10
引入依赖
首先我们要 Spring Boot 引入 spring-boot-starter-data-jpa 依赖。
Maven 配置:
org.springframework.bootspring-boot-starter-data-jpaorg.springframework.bootspring-boot-starter-weborg.springframework.bootspring-boot-devtoolsruntimeMysqLmysql-connector-javaruntime
Gradle 配置:
compile group: 'org.springframework.boot', name: 'spring-boot-starter-data-jpa', version: '2.0.5.RELEASE' compile group: 'org.springframework.boot', name: 'spring-boot-starter-web', version: '2.0.5.RELEASE' compile group: 'org.springframework.boot', name: 'spring-boot-devtools', version: '2.0.5.RELEASE' compile group: 'MysqL', name: 'mysql-connector-java', version: '6.0.6'
配置数据源
Spring Boot 提供了使用 application.properties 或 application.yml 文件配置项目属性的方法。我比较习惯使用 application.yml 文件,所以这里我只列出 application.yml 文件的写法。
spring: datasource: product: driver-class-name: com.MysqL.jdbc.Driver jdbc-url: jdbc:MysqL://127.0.0.1:3306/product?useUnicode=true&characterEncoding=utf-8&serverTimezone=UTC&autoReconnect=true&useSSL=false&zeroDateTimeBehavior=convertToNull username: root password: test123$ customer: driver-class-name: com.MysqL.jdbc.Driver jdbc-url: jdbc:MysqL://127.0.0.1:3306/customer?useUnicode=true&characterEncoding=utf-8&serverTimezone=UTC&autoReconnect=true&useSSL=false&zeroDateTimeBehavior=convertToNull username: root password: test123$ jpa: generate-ddl: true
配置好 application.yml 文件后分别在数据库创建 customer 和 product 数据库。
添加实体(Entity)类
客户实体:
package com.springboot.jpa.customer.models; import javax.persistence.*; @Entity public class Customer { @Id @GeneratedValue(strategy = GenerationType.IDENTITY) private Integer id; @Column(unique = true, nullable = false) private String email; private String firstName; private String lastName; protected Customer() { } public Customer(String email, String firstName, String lastName) { this.email = email; this.firstName = firstName; this.lastName = lastName; } @Override public String toString() { return String.format("Customer[id=%d, firstName='%s', lastName='%s',email='%s']", id, firstName, lastName, email); } public Integer getId() { return id; } public String getEmail() { return email; } public String getFirstName() { return firstName; } public String getLastName() { return lastName; } }
产品实体:
package com.springboot.jpa.product.models; import javax.persistence.*; @Entity public class Product { @Id @GeneratedValue(strategy = GenerationType.IDENTITY) private int id; @Column(nullable = false) private String code; private String name; private double price; protected Product() { } public Product(String code, String name, double price) { this.code = code; this.name = name; this.price = price; } @Override public String toString() { return String.format("Product[id=%d, code='%s', name='%s', price='%s']", id, code, name, price); } public int getId() { return id; } public String getCode() { return code; } public String getName() { return name; } public double getPrice() { return price; } }
添加数据仓库(Repository)类
客户 Repository:
package com.springboot.jpa.customer.repository; import com.springboot.jpa.customer.models.Customer; import org.springframework.data.jpa.repository.JpaRepository; import org.springframework.stereotype.Repository; @Repository public interface CustomerRepository extends JpaRepository { }
产品 Repository:
package com.springboot.jpa.product.repository; import com.springboot.jpa.product.models.Product; import org.springframework.data.jpa.repository.JpaRepository; import org.springframework.stereotype.Repository; @Repository public interface ProductRepository extends JpaRepository { }
添加配置(Config)类
客户配置:
package com.springboot.jpa.customer.config; import org.springframework.beans.factory.annotation.Qualifier; import org.springframework.boot.context.properties.ConfigurationProperties; import org.springframework.boot.jdbc.DataSourceBuilder; import org.springframework.boot.orm.jpa.EntityManagerFactoryBuilder; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.context.annotation.Primary; import org.springframework.data.jpa.repository.config.EnableJpaRepositories; import org.springframework.orm.jpa.JpaTransactionManager; import org.springframework.orm.jpa.LocalContainerEntityManagerfactorybean; import org.springframework.transaction.PlatformTransactionManager; import org.springframework.transaction.annotation.EnableTransactionManagement; import javax.persistence.EntityManagerFactory; import javax.sql.DataSource; @Configuration @EnableTransactionManagement @EnableJpaRepositories(entityManagerFactoryRef = "customerEntityManagerFactory", transactionManagerRef = "customerTransactionManager", basePackages = {"com.springboot.jpa.customer.repository"}) public class CustomerConfig { @Primary @Bean(name = "customerDataSource") @ConfigurationProperties(prefix = "spring.datasource.customer") public DataSource customerDataSource() { return DataSourceBuilder.create().build(); } @Primary @Bean(name = "customerEntityManagerFactory") public LocalContainerEntityManagerfactorybean entityManagerFactory(EntityManagerFactoryBuilder builder, @Qualifier("customerDataSource") DataSource dataSource) { return builder.dataSource(dataSource).packages("com.springboot.jpa.customer.models").persistenceUnit("customer").build(); } @Primary @Bean(name = "customerTransactionManager") public PlatformTransactionManager customerTransactionManager(@Qualifier("customerEntityManagerFactory") EntityManagerFactory customerEntityManagerFactory) { return new JpaTransactionManager(customerEntityManagerFactory); } }
产品配置:
package com.springboot.jpa.product.config; import org.springframework.beans.factory.annotation.Qualifier; import org.springframework.boot.context.properties.ConfigurationProperties; import org.springframework.boot.jdbc.DataSourceBuilder; import org.springframework.boot.orm.jpa.EntityManagerFactoryBuilder; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.data.jpa.repository.config.EnableJpaRepositories; import org.springframework.orm.jpa.JpaTransactionManager; import org.springframework.orm.jpa.LocalContainerEntityManagerfactorybean; import org.springframework.transaction.PlatformTransactionManager; import org.springframework.transaction.annotation.EnableTransactionManagement; import javax.persistence.EntityManagerFactory; import javax.sql.DataSource; @Configuration @EnableTransactionManagement @EnableJpaRepositories(entityManagerFactoryRef = "productEntityManagerFactory", transactionManagerRef = "productTransactionManager", basePackages = {"com.springboot.jpa.product.repository"} ) public class ProductConfig { @Bean(name = "productDataSource") @ConfigurationProperties(prefix = "spring.datasource.product") public DataSource dataSource() { return DataSourceBuilder.create().build(); } @Bean(name = "productEntityManagerFactory") public LocalContainerEntityManagerfactorybean barEntityManagerFactory(EntityManagerFactoryBuilder builder, @Qualifier("productDataSource") DataSource dataSource) { return builder.dataSource(dataSource).packages("com.springboot.jpa.product.models").persistenceUnit("product").build(); } @Bean(name = "productTransactionManager") public PlatformTransactionManager productTransactionManager(@Qualifier("productEntityManagerFactory") EntityManagerFactory productEntityManagerFactory) { return new JpaTransactionManager(productEntityManagerFactory); } }
项目结构:
src/main/java
- com.springboot.jpa
- product
- config
- models
- repository
- customer
- config
- models
- repository
添加测试类
客户测试类 CustomerDataSourcesTests:
package com.springboot.jpa; import com.springboot.jpa.customer.repository.CustomerRepository; import com.springboot.jpa.customer.models.Customer; import org.junit.runner.RunWith; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.boot.test.context.SpringBoottest; import org.springframework.test.context.junit4.springrunner; import org.springframework.transaction.annotation.Transactional; import org.junit.Test; import static org.junit.Assert.assertEquals; import static org.junit.Assert.assertNotNull; @RunWith(springrunner.class) @SpringBoottest public class CustomerDataSourcesTests { @Autowired private CustomerRepository customerRepository; @Test @Transactional("customerTransactionManager") public void createCustomer() { Customer customer = new Customer("master@weilog.net", "Charles", "Zhang"); customer = customerRepository.save(customer); assertNotNull(customerRepository.findById(customer.getId())); assertEquals(customerRepository.findById(customer.getId()).get().getEmail(), "master@weilog.net"); } }
产品测试类 ProductDataSourcesTests:
package com.springboot.jpa; import com.springboot.jpa.product.models.Product; import com.springboot.jpa.product.repository.ProductRepository; import org.junit.runner.RunWith; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.boot.test.context.SpringBoottest; import org.springframework.test.context.junit4.springrunner; import org.springframework.transaction.annotation.Transactional; import org.junit.Test; import static org.junit.Assert.assertNotNull; @RunWith(springrunner.class) @SpringBoottest public class ProductDataSourcesTests { @Autowired private ProductRepository productRepository; @Test @Transactional("productTransactionManager") public void createProduct() { Product product = new Product("10000", "Book", 80.0); product = productRepository.save(product); assertNotNull(productRepository.findById(product.getId())); } }
测试
分别运行两个测试类通过后,查询数据库。
客户表:
MysqL> SELECT * FROM customer; +----+-------------------+-----------+----------+ | id | email | firstName | lastName | +----+-------------------+-----------+----------+ | 1 | master@weilog.net | Charles | Zhang | +----+-------------------+-----------+----------+ 1 row in set
产品表:
MysqL> SELECT * FROM product; +----+-------+------+-------+ | id | code | name | price | +----+-------+------+-------+ | 1 | 10000 | Book | 80 | +----+-------+------+-------+ 1 row in set
