# Java-Spring依赖属性的setter方法注入值
1. 沿用上一个项目
+ 新建包
+ 拷贝之之前的类到新建的包里test.set
2. 删除构造方法并且为属性生成get&set方法
+ 删除构造方法
+ 生成get&set方法
**MyController.java**
```
package test.set;
public class MyController {
private MyService service;
public void login()
{
System.out.println("MyController login........");
service.serviceLogin();
}
public MyService getService() {
return service;
}
public void setService(MyService service) {
this.service = service;
}
}
```
**MyService** .java也是相同的操作
3. 修改配置文件
+ 先拷贝一个配置文件并且重命名以防冲突
+ 删除构造方法配置
+ 重写配置文件 beans_set.xml
```
```
4. 测试
+ 为咯验证是set方法注入在set方法内写入一段测试代码
```
public void setDao(MyDao dao) {
System.out.println("setDao()....");
this.dao = dao;
}
public void setService(MyService service) {
System.out.println("setService()");
this.service = service;
}
```
+ 更改没试类代码
```
package test.set;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class Test {
public static void main(String[] args) {
//实例化spring容器及bean
ApplicationContext act = new ClassPathXmlApplicationContext("beans_set.xml");
// 得到的是此处的controller
//
//
//
MyController c = (MyController) act.getBean("controller");
c.login();
}
}
```
**测试结果如下**
**备注：** 运行过程中有报过某个类红色告警不给过，解决方法为将这个类更改名称而后再次改回来则解决咯这个bug，究其原因是因为Eclipse软件件的bug
