添加依赖到 pom.xml
<!-- JUnit 输出日志用 -->
<dependency>

测试类提个基类
- 方便获取 bean
- 方便输出信息到控制台
package com.jerry;
import org.junit.Rule;
import org.junit.contrib.java.lang.system.SystemErrRule;
import org.junit.contrib.java.lang.system.SystemOutRule;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import junit.framework.TestCase;
/**
* 为了取 bean 方便提个基类。
*/
public class BaseTest extends TestCase {
//正确输出
@Rule
protected final static SystemOutRule out= new SystemOutRule();
//错误输出
@Rule
protected final static SystemErrRule err= new SystemErrRule();
//初始化 spring 上下文;
protected static ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");
public <T> T getBean(Class<T> requiredType) {
return context.getBean(requiredType);
}
public Object getBean(String requiredType) {
return context.getBean(requiredType);
}
/**
* 用于测试中,向控制台输出信息
* @author jerryjin
*/
protected static class log{
public static void out(String msg){
System.out.print(msg);
out.getLog();
}
public static void err(String msg){
System.err.print(msg);
err.getLog();
}
}
}
测试类
package com.jerry.service.impl;
import com.alibaba.fastjson.JSONObject;

import com.jerry.entity.Book;
import com.jerry.service.IBookService;
public class BookServiceTest extends BaseTest {
