Ant Hibernate MySQL CVS XML

Ant+XDoclet工具使用
Ant使用:
1、下载ant并解压到硬盘的某个位置
2、配置ant的环境变量ANT_HOME=D:\commons\apache-ant-1.7.1 path=%ANT_HOME%\bin
3、测试ant是否安装成功。
运行cmd命令(小窗口+r可以调出运行窗口键入cmd)进入dos窗口，键入ant回车运行得到
Buildfile: build.xml does not exist!
Build failed
这就说明ant安装成功。
4、创建build.xml文件

Xml代码

<? xml version = "1.0" encoding = "gbk" ?>
< project name = "测试脚本" default = "copyfile" basedir = "." >
< target name = "copyfile" >
< copy file = "d:/a.txt" todir = "e:/Temp" overwrite = "true" />
</ target >
</ project >

<?xml version="1.0" encoding="gbk"?>
<project name="测试脚本" default="copyfile" basedir=".">
    <target name="copyfile" >
        <copy  file="d:/a.txt" todir="e:/Temp" overwrite="true"/>
    </target>
</project>

直接运行ant,结果:
D:\>ant
Buildfile: build.xml
copyfile:
[copy] Copying 1 f
BUILD SUCCESSFUL
Total time: 0 seconds
测试ant成功!

**/CVS/*
两个**代表当前目录下的所有文件以及所有的子目录
/CVS代表当前目录下或者子目录下只要有CVS这个目录
/*代表CVS下的所有文件

XDoclet使用:
下载http://xdoclet.codehaus.org/
Ant+XDoclet:
OA工程里创建一个需要映射的对象

Java代码

package com.oa.model;
/**
* @author lukuijun
* @hibernate.class table="t_user"
*/
public class User {
/**
* @hibernate.id
* generator-class="native"
*/
private int id;
/**
* @hibernate.property
*/
private String username;
/**
* @hibernate.property
*/
private String password;
public int getId() {
return id;
}
public void setId( int id) {
this .id = id;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this .username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this .password = password;
}
}

package com.oa.model;
/**
 * @author lukuijun
 * @hibernate.class table="t_user"
 */
public class User {
	/**
	 * @hibernate.id
	 * generator-class="native"
	 */
	private int id;
	/**
	 * @hibernate.property
	 */
	private String username;
	/**
	 * @hibernate.property
	 */
	private String password;
	public int getId() {
		return id;
	}
	public void setId(int id) {
		this.id = id;
	}
	public String getUsername() {
		return username;
	}
	public void setUsername(String username) {
		this.username = username;
	}
	public String getPassword() {
		return password;
	}
	public void setPassword(String password) {
		this.password = password;
	}
}

建立build.xml

Xml代码

            </fileset>
            <component
                classname="org.xdoclet.plugin.hibernate.HibernateMappingPlugin"
                version="3.0"
                destdir="${src.dir}"
             />
        </xdoclet>
    </target>
</project>

说明一点:build.xml文件在保存的时候格式一定要和encoding="UTF-8"一致,否则报错Invalid byte 1 of 1-byte UTF-8 sequence.错误的原因就是因为xml指定了utf-8格式，但保存的时候不是utf-8编码，解决办法是用记事本打开之后，保存时候指定编码为utf-8编码。
下面运行ant就生成hibernate的配置文件和映射文件
