spring整合junit时遇到的问题

1、Could not autowire field: private javax.servlet.http.HttpServletRequest

参考：https://www.cnblogs.com/summary-2017/p/8000626.html

https://stackoverflow.com/questions/17619029/spring-junit-test-case-failed

@WebAppConfiguration("src/main/resources") : 注解在类上,用来声明加载的ApplicationContex 是一个WebApplicationContext ,它的属性指定的是Web资源的位置,默认为 src/main/webapp ,自定义修改为 resource

2、添加@WebAppConfiguration注解后又有错误： java.util.MissingResourceException: Can't find bundle for base name javax.servlet.LocalStrings, locale zh_CN

java.lang.ExceptionInInitializerError

报错原因：
Your running tests are missing the servlet-api dependency.
If you're using maven make sure this dependency is in your project:

<dependency>

    <groupId>javax.servlet</groupId>

    <artifactId>javax.servlet-api</artifactId>

    <version>3.1.0</version>

    <scope>provided</scope>

</dependency>

也可以将tomcat运行jar添加到buildpath，这样本地测试的时候使用Server Runtime里面的servlet.jar；但是使用maven打包项目时仍然会报错，所以最好还是在maven中添加依赖。

3、java.lang.NoClassDefFoundError: com/jayway/jsonpath/InvalidPathException

　　缺少了jar包，可以添加以下的maven依赖：

<dependency>

    <groupId>com.jayway.jsonpath</groupId>

    <artifactId>json-path</artifactId>

    <version>0.8.1</version>

    <scope>test</scope>

</dependency>

<dependency>

    <groupId>com.jayway.jsonpath</groupId>

    <artifactId>json-path-assert</artifactId>

    <version>0.8.1</version>

    <scope>test</scope>

</dependency>

            UtilFunctions.log.info("=== mvcResult:{} ===", mvcResult);

        } catch (Exception e) {

            e.printStackTrace();

　　测试Controller：请求参数是form表单类型或json

@Test

//            paramsJson.put("market", "eth_btc");

//            paramsJson.put("price", "0.03");

//            paramsJson.put("num", "1557.5425");

//            paramsJson.put("direction", "2");

//            paramsJson.put("trade_type", "1");

//            paramsJson.put("paypassword", "");

            String mvcResult = mockMvc.perform(

                post(uri).contentType(MediaType.APPLICATION_FORM_URLENCODED)

                // post(uri).contentType(MediaType.APPLICATION_JSON)

//                    .content(paramsJson.toJSONString()) // request json data

                    .param("market", "eth_btc")

                    .param("price", "0.03")

                    .param("num", "1557.5425")

                    //.param("direction", "1") // grpc return -19

                    .param("direction", "2")

                    .param("trade_type", "1")

                    .param("paypassword", "")

                    //.header("Cookie", PHPSESSIDKey + "=" + PHPSESSIDValue) // not ok

                    .cookie(cookiePHPSESSID)

                    //.requestAttr("uid", 106)

                    .accept(MediaType.parseMediaType("application/json;charset=UTF-8"))

            )

                .andDo(print())

                .andExpect(status().isOk())

                //.andExpect(content().contentType("application/json;charset=UTF-8"))

                .andExpect(jsonPath("$.code").value(0))

//                .andExpect(jsonPath("$.data.name", is("测试")))

//                .andExpect(jsonPath("$.data.createTime", notNullValue()))

                .andReturn().getResponse().getContentAsString();

            // === mvcResult:{"pay_pass":"3","code":0,"data":"2rhm0-1d85sc0ns-1-2"} ===

            UtilFunctions.log.info("=== mvcResult:{} ===", mvcResult);

        } catch (Exception e) {

            e.printStackTrace();

        }
