通过id名字进行自动装配
新建测试用的两个bean类：ClassRoom、Teacher
代码如下：
Teacher类：
public class Teacher {
private Integer teacherNo;
private String name;
/**
*
* @return the teacherNo
*/
public Integer getTeacherNo() {
return teacherNo;
}
/**
* @param teacherNo the teacherNo to set
*/
public void setTeacherNo(Integer teacherNo) {
this.teacherNo = teacherNo;
}
/**
*
* @return the name
*/
public String getName() {
return name;
}
/**
* @param name the name to set
*/
public void setName(String name) {
this.name = name;
}
/* (non-Javadoc)
* @see java.lang.Object#toString()
*/
@Override
public String toString() {
return "Teacher [teacherNo=" + teacherNo + ", name=" + name + "]";
}
ClassRoom类：
public class ClassRoom {
private String className;
private String classNo;
private Teacher teacher;
/**
*
* @return the className
*/
public String getClassName() {
return className;
}
/**
* @param className the className to set
*/
public void setClassName(String className) {
this.className = className;
}
/**
*
* @return the classNo
*/
public String getClassNo() {
return classNo;
}
/**
* @param classNo the classNo to set
*/
public void setClassNo(String classNo) {
this.classNo = classNo;
}
/**
*
* @return the teacher
*/
public Teacher getTeacher() {
return teacher;
}
/**
* @param teacher the teacher to set
*/
public void setTeacher(Teacher teacher) {
this.teacher = teacher;
}
/* (non-Javadoc)
* @see java.lang.Object#toString()
*/
@Override
public String toString() {
return "Class [className=" + className + ", classNo=" + classNo
+ ", teacher=" + teacher + "]";
}
}
配置文件如下：
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd"> <bean id="teacher" class="com.pfSoft.autowire.beans.Teacher" p:teacherNo="89757" p:name="L林俊杰"></bean> <bean id="classRoomBean" class="com.pfSoft.autowire.beans.ClassRoom" p:classNo="302" p:className="三年二班" autowire="byName"></bean> </beans>
关键点在于，autowire选择的是byName。同时id为“teacher”的bean，与ClassRoom类中seeter风格的属性名具有相同的名字。因此实现了通过名字进行自动装配。
同样的autowire="byType"是表示可以通过类型来进行自动匹配，不过需要注意的是如果同类型有多个bean的话就会报不只一个的异常了。
