SSM中利用MockMvc测试controller出现的几个问题
- Error creating bean with name ‘locationServiceImpl’
具体见以下log
十月 21, 2018 10:58:26 上午 org.springframework.web.context.support.GenericWebApplicationContext refresh
警告: Exception encountered during context initialization - cancelling refresh attempt
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'locationServiceImpl': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private ssm.zsc.first.dao.LocationMapper ssm.zsc.first.service.impl.LocationServiceImpl.locationMapper; nested exception is org.springframework.beans.factory.CannotLoadBeanClassException: Cannot find class [org.springframe.web.servlet.view.InternalResourceViewResolver] for bean with name 'org.springframe.web.servlet.view.InternalResourceViewResolver#0' defined in class path resource [spring-web.xml]; nested exception is java.lang.ClassNotFoundException: org.springframe.web.servlet.view.InternalResourceViewResolver

这里仅截取了一部分。
controller部分代码：
import java.util.HashMap;
import java.util.Map;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;
import ssm.zsc.first.pojo.LocationParam;
import ssm.zsc.first.service.LocationService;
@Controller
@RequestMapping("/location")
public class LocationController {
private Logger logger = LoggerFactory.getLogger(this.getClass());
@Autowired
private LocationService locationService;
@RequestMapping(value = "one.json",method = RequestMethod.POST)
@ResponseBody //将返回的map格式转换为json格式
public Map<String,Integer> addLocationToMysql(@RequestBody LocationParam locationParam){
System.out.println("into-------------------controller----method");
Map<String,Integer> map = new HashMap<String, Integer>();
int result = locationService.insertOrUp(locationParam);
map.put("result", result);
return map;
}
}
spring-web.xml部分：
<?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:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">
<!-- 配置springmvc -->
<!-- 1.开启springmvc注解模式 -->
<mvc:annotation-driven/>
<!-- 2.静态资源默认servlet配置 -->
<mvc:default-servlet-handler/>
<!-- 3.配置jsp显示viewResolver -->
<bean class="org.springframe.web.servlet.view.InternalResourceViewResolver">
<property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
<property name="prefix" value="/WEB-INF/jsp/"/>
<property name="suffix" value=".jsp"></property>
</bean>
<!-- 4.扫描web相关的bean -->
<context:component-scan base-package="ssm.zsc.first.controller"/>
</beans>
简要来说，controller内的方法需要接收以及返回的数据均为json格式，并没有返回ModelAndView，因此不需要InternalResourceViewResolver。把那一块的bean注释掉，问题消除。（个人理解）
- 一个低级错误
MockMvc测试部分代码：
import javax.servlet.ServletContext;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.MediaType;
import org.springframework.test.annotation.Rollback;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.web.WebAppConfiguration;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.ResultActions;
import org.springframework.test.web.servlet.request.MockMvcRequestBuilders;
import org.springframework.test.web.servlet.result.MockMvcResultMatchers;
import org.springframework.test.web.servlet.setup.MockMvcBuilders;
import org.springframework.transaction.annotation.Transactional;
import org.springframework.web.context.WebApplicationContext;
import com.fasterxml.jackson.databind.ObjectMapper;
import ssm.zsc.first.controller.LocationController;
import ssm.zsc.first.pojo.LocationParam;
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration({"classpath:spring-mybatis.xml","classpath:spring-service.xml","classpath:spring-web.xml"})
@Transactional
@WebAppConfiguration
public class ControllerTest {
@Autowired
private LocationController locationController;
//@Autowired
//private ServletContext context;
@Autowired
private WebApplicationContext context;
private MockMvc mockMvc;
@Before
public void setUp(){
//mockMvc = MockMvcBuilders.standaloneSetup(locationController).build();
mockMvc = MockMvcBuilders.webAppContextSetup(this.context).build();
System.out.println("mockMvc-Initial");
}
@Test
@Rollback(false)
public void ConTest() throws Exception{
//String requestBody = "{\"phoneNumber\":5431,\"longitude\":99.99,\"latitude\":11.11,\"status\":1}";
ObjectMapper mapper = new ObjectMapper();
LocationParam locationParam = new LocationParam();
locationParam.setPhoneNumber(9999);
locationParam.setLongitude(99.99);
locationParam.setLatitude(11.11);
locationParam.setStatus(1);
String json = mapper.writeValueAsString(locationParam);
System.out.println("before--------------------post");
System.out.println(json.toString());
ResultActions action = mockMvc.perform(MockMvcRequestBuilders.post("http://127.0.0.1:8080/location/one.json").contentType("application/json;charset=UTF-8").content(json).accept(MediaType.APPLICATION_JSON));
action.andExpect(MockMvcResultMatchers.content().contentType("application/json;charset=UTF-8")).andExpect(MockMvcResultMatchers.status().isOk());
System.out.println("after---------------------post");
}
}
在最开始的时候，MockMvcRequestBuilders.post()内写的网址为"localhost:8080/location/one.json"，导致一直没有数据库写入成功
后改为"http://127.0.0.1:8080/location/one.json"，成功。
成功后出现的log:

个人小白，欢迎交流。
