Hibernate Tools生成注释
获得源码的方法:
1.建立一个maven项目.
2.pox.xml修改为:
<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><groupId>com.pandy</groupId><artifactId>hibernate-tools</artifactId><version>0.0.1-SNAPSHOT</version><packaging>jar</packaging><name>hibernate-tools</name><url>http://maven.apache.org</url><properties><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding></properties><dependencies><dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>3.8.1</version><scope>test</scope></dependency><dependency><groupId>org.hibernate</groupId><artifactId>hibernate-tools</artifactId><version>4.0.0-CR1</version></dependency></dependencies><build><plugins><plugin><!-- 注解支持，jdk5才具有的新特性，我们需要设置compile插件，具体可以参考Setting the -source and -target of the Java Compiler，根据说明，我们继续向pom文件中加入 --><groupId>org.apache.maven.plugins</groupId><artifactId>maven-compiler-plugin</artifactId><configuration><source>5</source><target>5</target></configuration></plugin><plugin><!-- 我们想将所有的依赖库都打包，直接交给用户，这样用户不需要在做其他设置了，这里需要使用Assembly插件了，其说明参考Pre-defined Descriptor Files，这个参考文件也说明了有四种默认定义的打包方式，我们选择jar-with-dependencies，继续添加pom文件 --><artifactId>maven-assembly-plugin</artifactId><configuration><descriptorRefs><descriptorRef>jar-with-dependencies</descriptorRef></descriptorRefs></configuration></plugin></plugins></build></project>
