Java 弹簧启动测试:测试响应抛出“;找不到可接受的陈述“,应用程序工作正常
我正在使用SpringBoot创建一个应用程序。当我运行应用程序并测试服务时,我得到了正确的结果 但是,当我运行测试时,如下所示:Java 弹簧启动测试:测试响应抛出“;找不到可接受的陈述“,应用程序工作正常,java,spring,spring-mvc,testing,spring-boot,Java,Spring,Spring Mvc,Testing,Spring Boot,我正在使用SpringBoot创建一个应用程序。当我运行应用程序并测试服务时,我得到了正确的结果 但是,当我运行测试时,如下所示: public class CatalogControllerTet { private MockMvc mvc; @Autowired private WebApplicationContext context; @Autowired private CatalogRepository catalogRepository;
public class CatalogControllerTet {
private MockMvc mvc;
@Autowired
private WebApplicationContext context;
@Autowired
private CatalogRepository catalogRepository;
@Before
public void setUp() throws Exception {
this.mvc = MockMvcBuilders.webAppContextSetup(this.context).build();
}
@Test
public void getHello() throws Exception {
MvcResult r = mvc.perform(MockMvcRequestBuilders
.get("/catalogs")
.accept(MediaType.APPLICATION_JSON)).andReturn();
String content = r.getResponse().getContentAsString();
int i = 100;
}
}
当我在测试中设置断点时,我看到了这一点。我注意到的一点是,在“supportedMediaTypes”列表中没有看到任何提到JSON的内容
我看到了一些与我类似的问题,但它们可以追溯到响应对象没有任何getter/setter或与Jackson库有关的东西。服务启动并正确运行这一事实意味着它不是这些问题
非常感谢您在这方面提供的任何帮助。您的控制器的外观如下所示
package hello;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.bind.annotation.RequestMapping;
@RestController
public class HelloController {
@RequestMapping(value="/catalogs", produces={"application/json"})
@ResponseBody
public String catalogs() {
return "{\"catalogslist\":[], \"tupleslist\":[]}";
}
}
然后以下测试成功
package hello;
import static org.hamcrest.Matchers.equalTo;

测试成功

如果您需要一个样板,欢迎使用my进行新的spring boot项目。您只需克隆它并运行它:

一个更高级的示例实际上是从java对象创建json,然后对其进行测试
