emmmm..来一篇2018年的笔记吧.

小弟水平不高...

嗯..

主要是测试一下constructor-arg和property的使用示例笔记?

constructor-arg：通过构造函数注入。

property：通过setter对应的方法注入。

Employee.java

package com.glj.pojo;

public class Employee {
	private Integer age;
	private String name;
	public Integer getAge() {
		return age;
	}
	public void setAge(Integer age) {
		this.age = age;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	@Override
	public String toString() {
		return "Employee [age=" + age + ", name=" + name + "]";
	}
	public Employee() {
		super();
		// TODO Auto-generated constructor stub
	}
	public Employee(Integer age, String name) {
		super();
		this.age = age;
		this.name = name;
	}
	
}

使用springframework提供的单元测试

EmpolyeeTest.java

package com.glj.test;

import static org.junit.Assert.*;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.ApplicationContext;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import com.glj.pojo.Employee;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"classpath:ApplicationContext.xml"})
public class EmpolyeeTest {
	@Autowired
	ApplicationContext applicationContext;
	
	@Test
	public void testEmployee(){
		Employee employee = (Employee) applicationContext.getBean("employee");
		assertEquals(employee.getName(),"glj");
		System.out.println(employee.getName());
	}
}

其中：

@RunWith(SpringJUnit4ClassRunner.class)是junit4里用它来做junit加载器

@ContextConfiguration(locations={"classpath:ApplicationContext.xml"}) 主要用来加载spring的配置文件路径:是一个字符串数组,可以加载多个spring配置文件...
