#JiBX example

example like  [红色是酒][1]


##1 首先新建一个普通的maven项目 引入依赖
```xml
<dependency>
<groupId>org.jibx</groupId>
<artifactId>jibx-bind</artifactId>
<version>1.2.6</version>
</dependency>
```

##2 编写2个测试bean
```java
public class Account {
    private int id;
    private String name;
    private String email;
    private String address;
    private Birthday birthday;
    //getter、setter
    
    @Override
    public String toString() {
        return this.id + "#" + this.name + "#" + this.email + "#" + this.address + "#" + this.birthday;
    }
}

public class Birthday {
    private String birthday;
    public Birthday(String birthday) {
        super();
        this.birthday = birthday;
    }
    //getter、setter
    public Birthday() {}
     
    @Override
    public String toString() {
        return this.birthday;
    }
    public String getBirthday() {
        return birthday;
    }
    public void setBirthday(String birthday) {
        this.birthday = birthday;
    }
}
```
##3 准备开始编写数据绑定关系了，

+ 第一步是根据build.xml生成binding.xml描述文件,这一步也可以手动自己写，主要是描述实体和xml的映射关系。

+ 第二步是根据binding.xml编译生成中间操作类,实际上解码编码的时候都是用的生成的中间类，所以如果需要修改映射的时候也需要重新生成中间类.

+ ant文件如下,由于刚学ant，写的不好的地方多指教。主要是要在 compile编译的时候 指定destdir位子是maven项目的class位子。其中maven里面的jar文件路径自行修改下。

+ binggen是第一步，bind是第二步。生成好binding.xml后，第一步就不用每次都用ant编译了。

```
<?xml version="1.0" encoding="utf-8"?>
<project default="main" basedir=".">
    <path id="classpath">
        <dirset dir="${basedir}/target/classes" />
        <dirset dir="${basedir}/target/test-classes" />
        <fileset dir="D:/maven_repo/org/jibx/jibx-bind/1.2.6/" includes="*.jar" />
        <fileset dir="D:/maven_repo/org/jibx/jibx-run/1.2.6/" includes="*.jar" />
        <fileset dir="D:/maven_repo/bcel/bcel/5.1/" includes="*.jar" />
    </path>
    <target name="main" depends="compile,binggen, bind" description="Main target" />
    <target name="compile" description="Compilation target">
        <echo>Building file.</echo>
        <javac srcdir="${basedir}/src/main/java" destdir="${basedir}/target/classes" includeantruntime="true" />
    </target>
    <target name="binggen">
        <echo message="Running BindGen tool" />
        <java classpathref="classpath" fork="true" failonerror="true" classname="org.jibx.binding.BindingGenerator">
            <arg value="com.keeley.Account" />
        </java>
    </target>
    <target name="bind">
        <echo message="Running bind" />
        <taskdef name="bind" classname="org.jibx.binding.ant.CompileTask">
            <classpath refid="classpath"/>
        </taskdef>
        <bind binding="${basedir}/binding.xml">
            <classpath refid="classpath"/>
        </bind>
    </target>
</project>
```
 然后看target目录  应该多出很多 JiBX_开头的class文件。 
 
##4 编写测试类
:smile:
```java
public class JibxTest {
	private IBindingFactory factory = null;
	private StringWriter writer = null;
	private StringReader reader = null;
	private Account bean = null;
	@Before
    public void init() {
	    bean = new Account();
	    bean.setAddress("北京");
	    bean.setEmail("email");
	    bean.setId(1);
	    bean.setName("jack");
	    Birthday day = new Birthday();
	    day.setBirthday("2010-11-22");
	    bean.setBirthday(day);
	    try {
	        factory = BindingDirectory.getFactory(Account.class);
	    } catch (JiBXException e) {
	        e.printStackTrace();
	    }
	}
	@After
	public void destory() {
	    bean = null;
	    try {
	        if (writer != null) {
	            writer.flush();
	            writer.close();
	        }
	        if (reader != null) {
	            reader.close();
	        }
	    } catch (IOException e) {
	        e.printStackTrace();
	    }
	}
	@Test
	public void bean2XML() {
	    try {
	        writer = new StringWriter();
	        // marshal 编组
	        IMarshallingContext mctx = factory.createMarshallingContext();
	        mctx.setIndent(2);
	        mctx.marshalDocument(bean, "UTF-8", null, writer);
	        fail(writer);
	        reader = new StringReader(writer.toString());
	        //unmarshal 解组
	        IUnmarshallingContext uctx = factory.createUnmarshallingContext();
	        Account acc = (Account) uctx.unmarshalDocument(reader, null);
	        fail(acc);
	    } catch (Exception e) {
	        e.printStackTrace();
	    }
	}
	public void fail(Object o) {
	    System.out.println(o);
	}
	public void failRed(Object o) {
	    System.err.println(o);
	}
}
