seasar的helloworld以及三种注入方式

qbq

1.IHelloWorld接口
package org.tie.seasar1.service;
public interface IHelloWorld {
public void sayHello();
public void constructDI();
public void seterDI();
public void methodDI();
}
2.IHelloWorld接口的实现
package org.tie.seasar1.service.impl;
import org.tie.seasar1.service.IHelloWorld;
public class HelloWorld implements IHelloWorld {
private String msg1;
private String msg2;
private String msg3;
public String getMsg2() {
    return msg2;
}
public void setMsg2(String msg2) {
    this.msg2 = msg2;
}
public HelloWorld(String msg1) {
    super();
    this.msg1 = msg1;
}
public void sayHello() {
    System.out.println("hello world");
}
public void constructDI() {
    System.out.println(msg1);
}
public void seterDI() {
    System.out.println(msg2);
}
public void init(String msg3) {
    this.msg3 = msg3;
}
public void methodDI(){
    System.out.println(msg3);
}
}
3.客户端测试类
package org.tie.seasar1.client;
import org.apache.log4j.Logger;
import org.seasar.framework.container.S2Container;
import org.seasar.framework.container.factory.S2ContainerFactory;
import org.tie.seasar1.service.impl.HelloWorld;
public class HelloWorldClient {
private static final Logger log = Logger.getLogger(HelloWorldClient.class);
private static final String PATH = "dicon/helloworld.dicon";
public static void main(String[] args) {
S2Container container = S2ContainerFactory.create(PATH);
    container.init();
    HelloWorld helloWorld = (HelloWorld) container
      .getComponent("helloWorld");
    helloWorld.sayHello();
    helloWorld.constructDI();
    helloWorld.seterDI();
    helloWorld.methodDI();
    log.info("quick start");
}
}
4.DI配置文件：helloworld.dicon

    "构造函数注入"
    "设定函数注入"
   
              "方法函数注入"
         
  
    aop.traceInterceptor                                        ------------AOP拦截器
