Spring web项目开发

一、Spring MVC 项目搭建

二、Spring MVC 集成 MyBatis

三、Spring MVC 实现CRUD功能

四、Spring MVC 集成log4j

五、Spring MVC 集成Junit

---

创建一个单独的测试模块

将spring-mybatis-sample-war模块下的配置文件拷贝到spring-mybatis-sample-test下

注意：此处先移除spring-servlet.xml中的如下配置

<mvc:annotation-driven/>

POM依赖

BaseTest.java

package spring.mybatis.sample;

import org.junit.runner.RunWith;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringRunner;

/**
 * Created by liuquan on 2019/3/24.
 */
@RunWith(SpringRunner.class)
@ContextConfiguration(locations = {"classpath:/spring-config/spring-context.xml","classpath:/spring-config/spring-servlet.xml"})
public class BaseTest {
}

BaseServiceTest.java

package spring.mybatis.sample;

/**
 * Created by liuquan on 2019/3/24.
 */
public class BaseServiceTest extends BaseTest {
}

UserServiceTest.java

package spring.mybatis.sample.basic.user;

import org.junit.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.util.Assert;
import spring.mybatis.sample.BaseServiceTest;
import spring.mybatis.sample.basic.user.bo.UserBO;
import spring.mybatis.sample.basic.user.service.UserService;

/**
 * Created by liuquan on 2019/3/24.
 */
public class UserServiceTest extends BaseServiceTest {

    @Autowired
    private UserService userService;

    @Test
    public void testQueryOneUser(){

        UserBO userBO = new UserBO();
        userBO.setId("5");
        UserBO oldUserBO = userService.queryOneUser(userBO);

        Assert.notNull(oldUserBO, "未查询对应的用户信息");
        Assert.isTrue(oldUserBO.getAge() == 18, "年龄不是18");

    }

    @Test
    public void testUpdateUser(){
        UserBO userBO = new UserBO();
        userBO.setId("5");
        userBO.setAge(19);
        Integer updateNum = userService.updateUser(userBO);

        Assert.isTrue(updateNum == 1, "更新失败");

    }
}

先执行testUpdateUser()，更新成功后，执行testQueryOneUser()

测试完Service我们来测试Controller
POM

        <dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>javax.servlet-api</artifactId>
            <version>3.0.1</version>
        </dependency>

spring-servlet.xml文件中添加如下代码

<mvc:annotation-driven/>

BaseControllerTest.java

package spring.mybatis.sample;

import org.springframework.test.context.web.WebAppConfiguration;

/**
 * Created by liuquan on 2019/3/24.
 */
@WebAppConfiguration(value = "src/test/resources")
public class BaseControllerTest extends BaseTest{
}

UserControllerTest.java

package spring.mybatis.sample.basic.user;

import org.junit.Before;
import org.junit.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.MediaType;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.ResultActions;
import org.springframework.test.web.servlet.request.MockHttpServletRequestBuilder;
import org.springframework.test.web.servlet.request.MockMvcRequestBuilders;
import org.springframework.test.web.servlet.setup.MockMvcBuilders;
import org.springframework.web.context.WebApplicationContext;
import spring.mybatis.sample.BaseControllerTest;


import static org.springframework.test.web.servlet.result.MockMvcResultHandlers.print;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;


/**
 * Created by liuquan on 2019/3/24.
 */
public class UserControllerTest extends BaseControllerTest{

    @Autowired
    private WebApplicationContext webApplicationContext;

    private MockMvc mockMvc;

    @Before
    public void setUp() throws Exception {
        mockMvc = MockMvcBuilders.webAppContextSetup(webApplicationContext).build();
    }

    @Test
    public void queryOneUser() throws Exception {
        MockHttpServletRequestBuilder mockHttpServletRequestBuilder = MockMvcRequestBuilders.post("/userController/query-user-detail.json");
        mockHttpServletRequestBuilder.contentType(MediaType.APPLICATION_FORM_URLENCODED);
        mockHttpServletRequestBuilder.param("id", "5");
        ResultActions resultActions = mockMvc.perform(mockHttpServletRequestBuilder);
        resultActions.andExpect(status().isOk());
        resultActions.andDo(print());
        String responseStr = resultActions.andReturn().getResponse().getContentAsString();
        System.out.println(responseStr);
    }

}
