Spring中空值的写法

1、Member类

[java]
package www.csdn.spring1.dao;

public class Member {

private String name;
private Dept dept;
public void setName(String name) {
this.name = name;
}
public void setDept(Dept dept) {
this.dept = dept;
}
@Override
public String toString() {
return "Member [name=" + name + ", dept=" + dept + "]";
}

}

package www.csdn.spring1.dao;

public class Member {

private String name;
private Dept dept;
public void setName(String name) {
this.name = name;
}
public void setDept(Dept dept) {
this.dept = dept;
}
@Override
public String toString() {
return "Member [name=" + name + ", dept=" + dept + "]";
}

}

2、Dept类

[java]
package www.csdn.spring1.dao;

public class Dept {

private String name;
private String deptno;
public void setName(String name) {
this.name = name;
}
public void setDeptno(String deptno) {
this.deptno = deptno;
}

}

package www.csdn.spring1.dao;

public class Dept {

private String name;
private String deptno;
public void setName(String name) {
this.name = name;
}
public void setDeptno(String deptno) {
this.deptno = deptno;
}

}

3、xml文件

[html]
< xml version="1.0" encoding="UTF-8" >
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd">

< xml version="1.0" encoding="UTF-8" >
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd">

4、测试类

[java]
package www.csdn.spring1.test;

import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import www.csdn.spring1.dao.Member;

public class NullTest {

@Test
public void nullTest(){
ApplicationContext context=new ClassPathXmlApplicationContext("classpath:spring-null.xml");
Member m=context.getBean("member", Member.class);
System.out.println(m.toString());
}
}
