1、maven依赖

<properties>    <org.springframework.version>4.2.4.RELEASE</org.springframework.version>    <java.version>1.7</java.version>    <maven.compiler.version>3.1</maven.compiler.version>    <junit.version>4.12</junit.version>    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding></properties>    <dependencies><!-- Spring Test -->        <dependency>            <groupId>org.springframework</groupId>            <artifactId>spring-test</artifactId>            <version>${org.springframework.version}</version>        </dependency>        <dependency>            <groupId>junit</groupId>            <artifactId>junit</artifactId>            <version>4.12</version>            <scope>test</scope>        </dependency>    </dependencies>

2、注解配置

package com.ricky.codelab.spring;import org.junit.Test;import org.junit.runner.RunWith;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.test.context.ContextConfiguration;import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;import com.ricky.codelab.spring.aop.service.HelloService;/** * Spring4 + Junit4集成 * @author Ricky * */@RunWith(SpringJUnit4ClassRunner.class)@ContextConfiguration(locations="classpath:spring-annotation.xml")public class HelloServiceTest {    @Autowired    private HelloService helloService;    @Test    public void testHello(){        helloService.sayHello("ricky");    }}

解释下用到的注解:

@RunWith：用于指定junit运行环境，是junit提供给其他框架测试环境接口扩展，为了便于使用spring的依赖注入，spring提供了org.springframework.test.context.junit4.SpringJUnit4ClassRunner作为Junit测试环境
@ContextConfiguration:用于指定spring配置环境
@TransactionConfiguration:用于配置事务
@Transactional:表示所有类下所有方法都使用事务

spring-annotation.xml

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"      xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx"      xsi:schemaLocation="          http://www.springframework.org/schema/beans          http://www.springframework.org/schema/beans/spring-beans-4.0.xsd          http://www.springframework.org/schema/context          http://www.springframework.org/schema/context/spring-context-4.0.xsd          http://www.springframework.org/schema/tx          http://www.springframework.org/schema/tx/spring-tx-4.0.xsd">      <context:annotation-config/>    <context:component-scan base-package="com.ricky.codelab.spring" /></beans>
