springboot 之web进阶

SpringBoot 使用 WEB 进阶（springboot webjars）

1. 使用 aop 处理请求 get，post

2. 统一异常检查

3. 单元测试

4 效果预览：

5. 开发环境

maven 开发环境：3.3.9

Itellij IDEA 旗舰版

java 开发环境 java version "1.8.0_91"

6. 完成的完整的代码实例

idea：spring initializr 无 web 勾选，maven 方式搭建 springboot 项目。jdk7 创建 springboot 项目的版本不兼容问题。

一、idea 使用 spring initializr 不选择 web 搭建 springboot 项目

1.file => new => project

2. 直接 next 到 finish 结束。

3. 完成后创建 controller 用例测试

4.pom 文件

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>

    <name>boot-demo</name>
    <description>Demo project for Spring Boot</description>

    <properties>
        <java.version>1.8</java.version>
    </properties>

    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter</artifactId>

            </plugin>
        </plugins>
    </build>

</project>

5.application.properties

#端口号修改。默认8080
server.port=

6.springboot 入口启动类

package cc.ash.bootdemo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Configuration;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

@SpringBootApplication
@Controller
public class BootDemoApplication {


    @RequestMapping("/boot")
    @ResponseBody
    public String bootTest() {

        return "hello springboot";
    }
    public static void main(String[] args) {
        SpringApplication.run(BootDemoApplication.class, args);
    }

}

7. 新建包下 controller 测试类

package cc.ash.bootdemo.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class TestController {

    @RequestMapping(name="springboot test", value = "/test")
    public String test() {
        return "booted";
    }
}

8. 运行结果

新建包下 controller 测试类：访问页面

springboot 启动类中访问 404。改 requestMapping、rerun，做了很多操作到怀疑人生。重启 idea，世界终于正常了。

能正常访问的结果如下

二、maven 搭建 springboot 项目

1.jdk7 的情况下

2.maven 搭建

创建完成后的项目结构和 pom 文件。一个字就是干净

3. 手动添加 pom 依赖

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>


    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.1.7.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>


    <groupId>cc.ash</groupId>
    <artifactId>boot-demo</artifactId>
    <version>1.0-SNAPSHOT</version>


    <properties>
        <java.version>1.8</java.version>
    </properties>

    <!--  =================jdk1.7与springboot版本不兼容=======================  -->
    <!--<properties>
        <java.version>1.7</java.version>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <start-class>com.myproject.Application</start-class>
    </properties>-->

    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>

        <!--  手动添加web依赖，@restController @requestMapping注解等      -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>
</project>

maven 导入依赖（未选择自动导入的情况下）。

4. 编写测试用例代码

1). 测试 controller：

　　TestController

package cc.ash.controller;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class TestController {

    @RequestMapping(name="maven手动创建springboot",value={"/manual", "mvnManual"})
    @ResponseBody
    public String test() {

        return "maven manual";
    }

}

2. 启动入口：

DemoApplication

package cc.ash;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class DemoApplication {
    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }
}

3. 完成后代码结构

5. 访问测试

6.jdk1.7 错误留存

不兼容问题

https://blog.csdn.net/wj197927/article/details/79557017

https://www.jianshu.com/p/95d8a0cf0244

idea 日志记录（非控制台日志，控制台日志如上）

7.springboot 项目结构导致 controller 访问 404 的问题

自建的所有需要扫描注解的类，必须与启动类的包平级或者在其之下。如启动类在包【aa.bb】，其他需要扫描的类必须在【aa.bb】中或【aa.bb】之下的包里。

java-study-springboot-基础学习-05-springboot web开发

SpringBoot 之web开发

1、自动配置类说明

Web开发的自动配置类： org.springframework.boot.autoconfigure.web.WebMvcAutoConfiguration

比如：
spring mvc的前后缀配置

在WebMvcAutoConfiguration中对应方法

对应配置文件

2、静态资源配置说明

如果进入SpringMVC的规则为/时，SpringBoot的默认静态资源的路径为：
spring.resources.static-locations=classpath:/META-INF/resources/,classpath:/resources/,classpath:/static/,classpath:/public/
如果某个静态文件不在上面的配置路径中，那么从浏览器中就访问不到了

3、自定义消息转化器

原有的spring mvc 配置

springboot 配置

4、自定义拦截器

继承org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter

参考：https://github.com/chengbingh...

方式一：

@Aspect
@Component
public class HttpAspect {

    @Before("execution(public * com.imooc.girl.controller.GirlController.*(..))")
    public void log(){
        System.out.println("1111111111");
    }

    @After("execution(public * com.imooc.girl.controller.GirlController.*(..))")
    public void doAfter(){
        System.out.println("222222222");
    }

}

优化后：

@Aspect
@Component
public class HttpAspect {

    @Pointcut("execution(public * com.imooc.girl.controller.GirlController.*(..))")
    public void log(){

    }
    
    @Before("log()")
    public void doBefore(){
        System.out.println("1111111111");
    }

    @After("log()")
    public void doAfter(){
        System.out.println("222222222");
    }

}

在优化：

@Aspect
@Component
public class HttpAspect {

    private final static Logger logger = LoggerFactory.getLogger(HttpAspect.class);

    @Pointcut("execution(public * com.imooc.girl.controller.GirlController.*(..))")
    public void log(){

    }

    @Before("log()")
    public void doBefore(JoinPoint joinPoint){
        logger.info("1111111111");
        ServletRequestAttributes attributes=(ServletRequestAttributes)RequestContextHolder.getRequestAttributes();
        HttpServletRequest request=attributes.getRequest();
        //url
        logger.info("url={}",request.getRequestURL());
        //method
        logger.info("method={}",request.getMethod());
        //ip
        logger.info("method={}",request.getRemoteAddr());
        //类方法
        logger.info("class_method={}",joinPoint.getSignature().getDeclaringTypeName()+"."+joinPoint.getSignature().getName());
        //参数
        logger.info("args={}",joinPoint.getArgs());
    }

    @After("log()")
    public void doAfter(){
        logger.info("222222222");
    }

}

如果需要获取返回的值：

@AfterReturning(returning = "object",pointcut = "log()")
public void doAfterReturning(Object object){
    logger.info("response={}",object);
}

1.由于需要统一的返回格式，所以，封装了返回对象Result

2.由于代码封装成功、失败等。高重复动作，封装工具类ResultUtil。

3.由于在逻辑处理时，牵扯很多种非法状态。service进行判断，获取逻辑--》返回controller，判断状态继续处理。

改良:service逻辑判断非法,抛出异常-->controller继续抛出-->统一异常类进行处理,调用工具类。

4.由于Exception只能有描述，没有状态值。难以返回。自定义GrilException（id+msg）。

5.由于每次都要输入状态值，状态描述。为了统一管理，将其封装到enum(数据字典),统一管理
