1.所需jar包

下載地址：http://search.maven.org/

搜索junit-4.12-beta-1

　　aspectjweaver-1.8.2

　　sPRing-test-4.0.6.RELEASE

2.3中測(cè)試形式

（1）最古老的

package sy.test;import org.junit.Test;import org.junit.runner.RunWith;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.beans.factory.annotation.Qualifier;import org.springframework.context.applicationContext;import org.springframework.context.support.ClassPathxmlApplicationContext;import org.springframework.test.context.ContextConfiguration;import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;import sy.model.User;import sy.service.IUserService;//@RunWith(SpringJUnit4ClassRunner.class)//@ContextConfiguration(locations={"classpath:spring.xml","classpath:spring-mybatis.xml"})public class TestMybatis {        //使用test注解    @Test    public void test1(){        //讀取配置文件，如有多個(gè)，用逗號(hào)隔開        ApplicationContext ctf =                 new ClassPathXmlApplicationContext(new String[]{"spring.xml","spring-mybatis.xml"});        //獲取userService實(shí)例        IUserService userService = (IUserService) ctf.getBean("userService");        User user = userService.getUserById("0");        System.out.println(user);    }    }

　　(2).如果有多個(gè)test，則spring每次都要去加載讀取上下文，很浪費(fèi)資源，因此

package sy.test;import org.junit.Before;import org.junit.Test;import org.junit.runner.RunWith;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.beans.factory.annotation.Qualifier;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;import org.springframework.test.context.ContextConfiguration;import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;import sy.model.User;import sy.service.IUserService;//@RunWith(SpringJUnit4ClassRunner.class)//@ContextConfiguration(locations={"classpath:spring.xml","classpath:spring-mybatis.xml"})public class TestMybatis {        private IUserService userService;    private ApplicationContext ctf;    @Before    public void before(){        ctf = new ClassPathXmlApplicationContext(new String[]{"spring.xml","spring-mybatis.xml"});         userService = (IUserService) ctf.getBean("userService");    }        //使用test注解    @Test    public void test1(){        User user = userService.getUserById("0");        System.out.println(user);    }        //使用autowired注解    @Autowired    public void setUserService(IUserService userService) {        this.userService = userService;    }        }

@Before注解會(huì)在所有test測(cè)試之前執(zhí)行

(3)spring與junit整合

package sy.test;import org.junit.Before;import org.junit.Test;import org.junit.runner.RunWith;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.beans.factory.annotation.Qualifier;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;import org.springframework.test.context.ContextConfiguration;import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;import sy.model.User;import sy.service.IUserService;@RunWith(SpringJUnit4ClassRunner.class)@ContextConfiguration(locations={"classpath:spring.xml","classpath:spring-mybatis.xml"})public class TestMybatis {        private IUserService userService;        //使用test注解    @Test    public void test1(){        User user = userService.getUserById("0");        System.out.println(user);    }        //使用autowired注解    @Autowired    public void setUserService(IUserService userService) {        this.userService = userService;    }        }
