Boa constrictor plankton

我想填充一些百分比值，以便在小数点前总是有3个单位。使用整数，我可以使用’％03d’-浮点数是否等效？

‘％.3f’适用于小数点后的位，但’％03f’不执行任何操作。

答案1

‘％03.1f’有效（1可以是任何数字或空字符串）：

>>> "%06.2f"%3.3''003.30''>>> "%04.f"%3.2''0003''

请注意，字段宽度包括小数位和小数位。

@builder,@NoArgsConstructor,@AllArgsConstructor,@Getter,@Setter注解—lombok注解遇到的问题

在开发过程中，lombok的使用极大的简化了实体类的开发工作。在通常情况下我们需要手动去建立getter和setter方法，构造函数之类的，而lombok的作用就是能够在我们编译源码的时候自动帮我们生成这些方法，这些都是通过注解的方式：如@builder,@NoArgsConstructor,@AllArgsConstructor,@Getter,@Setter,@data等等。

a.添加lombok的pom依赖：

<dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <version>0.10.2</version>
</dependency>

在idea编译器，可以在下载对应版本的lombok插件，这样项目中就可以对于实体类进行简化开发了。

b.@builder注解使用的问题：

@Builder声明实体，表示可以进行Builder方式初始化，@Value注解，表示只公开getter，对所有属性的setter都封闭，即private修饰，所以它不能和@Builder在一起用

（在我看来，就是相当于将对象的set方法简化，在业务需求开发中，如果set的情况较多就可以使用，这样可以提高代码简洁度，下面是我使用@builder的方法）

在实体类中加上@Builder注解，在service层即可使用：

//实质上，就是对象的setId(),setName()
Object object =object.builder().Id("123”).name(“张三”).build();

但是在使用JPA的findone方法的时候，报错：没有默认的构造器，我推测是因为在加上@builder使JPA的默认构造器失效了，因此查阅了资料发现lombok中存在两个关于默认构造器的注解：@NoArgsConstructor（自动生成无参数构造函数）,@AllArgsConstructor（自动生成全参数构造函数），于是尝试着在实体类上加了这两个注解，果然在使用JPA时就不会报错了，所以建议在没有遇到set方法使用过于繁多的情况下就不要用这个@builder了，可能是与对象关系映射的持久层框架有冲突。

c.总结：lombok极大的提高了我们的开发效率，java语言日新月异，难免遇到各类问题，还是活到老，学到老为妙！

lombok也存在其他的很实用的注解，比如@Data: 自动为所有字段添加@ToString, @EqualsAndHashCode, @Getter方法，为非final字段添加@Setter,和@RequiredArgsConstructor，技术很菜，希望可以多多学习！

Access restriction: The constructor BASE64Encoder(

Access restriction: The constructor BASE64Encoder() is not accessible due to restriction on required library D:\Program Files\Java\jdk1.6.0_35\jre\lib\rt.jar

在Eclipse中编写Java代码时，用到了BASE64Decoder，import sun.misc.BASE64Decoder;可是Eclipse提示： 
Access restriction : The type BASE64Decoder is not accessible due to restriction on required library C:\Program 
files\java\jre6\lib\rt.jar 
Access restriction : The constructor BASE64Decoder() is not accessible due to restriction on required library C:\Program files\java\jre6\lib\rt.jar 
搞不懂是为什么，最后在http://forums.dzone.com/eclipse/384-access-restriction-problems.html找到答案，只需要在project build path中先移除JRE System Library，再添加库JRE System Library，重新编译后就一切正常了。但是我仍然很疑惑是为什么。。。

Windows -> Preferences -> Java -> Compiler -> Errors/Warnings -> 
Deprecated and trstricted API -> Forbidden reference (access rules): -> change to warning 
  
我这样解决的！

Boa Constructor的网友评论

boa-constructor是一个跨平台的Python集成开发环境和wxPython图形用户界面构建器。它提供了可视化方式的框架（窗口） 的创建 和处理、对象检视器(object inspector)、编辑器、继承的等级、html文档字符串、高级的调试器和集成化的帮助系统。俨然一个用于 Python的Delphi。

对的Zope支持：对象的创建和编辑。剪切，复制，粘贴，导入和导出。检视器(inspector)和Python脚本调试中的创建和编辑。

boa- constructor是用Python和wxPython库写成的。使用它之前，你必须安装了wxPython 2.4.0.7或wxPython更高 的版本以及Python 2.1或Python的更高的版本。建议在使用boa-constructor之前，先入门wxPython。

Bouygues Construction falls victim to ransomware

http://www.zdnet.com/article/bouygues-construction-falls-victim-to-ransomware/

Bouygues Construction has confirmed falling victim to ransomware that it detected across its network on January 30.

"As a precautionary measure, information systems have been shut down to prevent any propagation," the company said in a brief statement.

"Our teams are currently fully focused on returning to normal as quickly as possible, with the support of experts.

"Installations are progressively being put back into service after being tested."

Bouygues took to Twitter over the weekend to announce the attack.

"The @Bouygues_C computer network has been the victim of an act of cybercrime. We are doing everything we can to get back to normal as soon as possible. We are in close contact with our customers and partners as well as the relevant authorities," the company tweeted.

Bouygues said operational activity on its construction sites had not been disrupted, and that its personnel was "working flat out to ensure that our operations continue as smoothly as possible under these conditions, so that impact on our customers and partners is minimised".

"We are in close contact with them and with the relevant authorities," it added.

ZDNet understands the Maze ransomware group was behind the attack, with Bouygues'' data being published online.

Maze recently created a website on the public internet where they listed all the victim companies who didn''t pay and have started leaking some of their data.

Information relating to the victim''s employees has included names, home addresses, phone numbers, social insurance numbers, banking details, and drug test results.

Bouygues is headquartered in France, but its Australian arm is currently contracted on a handful of civil projects, including Sydney''s NorthConnex, Melbourne''s Metro Tunnel, the Go Between Bridge -- a 280-metre bridge crossing the Brisbane River, and the Sydney Airport Link.

It is understood medical imaging and radiotherapy equipment provider United Imaging has also been hit by Maze, with a data dump available on the ransomware gang''s website labelled "Australian".
