【原创】基于spring 3.1.0 两种依赖注入的测试代码

编写 SetterInjection 的测试用例

 

TestSetterInjection 直接继承于 Spring 所提供的 AbstractJUnit4SpringContextTests 的抽象测试类。

 

TestSetterInjection.java代码：

 

import org.junit.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.AbstractJUnit4SpringContextTests;
import org.wh.tech.spring.di.SetterInjection;

/**
 * @Author:WangHuan
 * 
 * @Date:2011-7-1
 * 
 * @TODO:测试Setter方式注入
 */

@ContextConfiguration(locations={"classpath:applicationContext-di.xml"})
public class TestSetterInjection extends AbstractJUnit4SpringContextTests {
	
	@Autowired  //
	private SetterInjection setterInjection;
	
	@Test
	public void getObject(){
		setterInjection.getObject();
	}

}

 

 

 

SetterInjection.java代码：

 

package org.wh.tech.spring.di;


/**
 * @Author:WangHuan
 * 
 * @Date:2011-7-1
 *
 * @TODO:用setter方式注入
 */

public class SetterInjection implements DiService {

	private String arg0;
	private String arg1;
	
	
	public void setArg0(String arg0) {
		this.arg0 = arg0;
	}


	public void setArg1(String arg1) {
		this.arg1 = arg1;
	}


	public String getArg0() {
		return arg0;
	}


	public String getArg1() {
		return arg1;
	}


	/* (non-Javadoc)
	 * @see org.wh.tech.spring.di.DiService#getObject()
	 */
	@Override
	public Class<?> getObject() {
		// TODO Auto-generated method stub
		System.out.println(this.getArg0() + " ; " + this.getArg1());
		return this.getClass();
	}

}

 

applicationContext-di.xml代码：

		<property name="arg0" value="0" />
		<property name="arg1" value="1" />
	</bean>
</beans>

 

 

编写 ConstructorInjection 的测试用例

 

主要差别的配置如下

	<bean id="constructorInjection" class="org.wh.tech.spring.di.ConstructorInjection" scope="prototype">
		<constructor-arg type="java.lang.String">
			<value>test</value>
		</constructor-arg>
		<constructor-arg type="int">
			<value>70</value>
		</constructor-arg>		
	</bean>
