我正在尝试为Spring编写一个Junit测试用例,经过大量的阅读后,我得到了一切可以返回text / plain的方法。当我试图返回application / json时,我遇到了问题。
关于SO的共识似乎是:使用mvc:annotation-driven。我试过这个(通过根据here创建下面显示的spring-web-servlet.xml。然而,这并没有解决我的问题。任何人都知道我还在做错什么?
spring-web-servlet.xml(在WEB-INF文件夹中)
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.2.xsd">
<mvc:resources mapping="/resources/**" location="/resources/" />
<mvc:annotation-driven />
</beans>
有问题的方法(在HelloService类中)
@GET
@RequestMapping("/json2")
@Produces({"application/json"})
@ResponseBody
public Object getUserInfoJSON(@RequestParam(value="p",defaultValue="0") Integer userId){
try (Connection conn = conn()) {
String query = "SELECT * FROM pulse.customer WHERE userId = ?";
PreparedStatement preparedStmt = conn.prepareStatement(query);
preparedStmt.setInt(1, userId);
ResultSet rs=preparedStmt.executeQuery();
if(rs.next())
return Json.createObjectBuilder().add("login name", rs.getString("loginName"));
return Json.createObjectBuilder().add("login name", "shit broke yo!!!");
}
catch(SQLException s){
return "sql exception:"+s.toString();
}
catch (NoResultException nre) {
//throw new UserNotFoundException(userId);
return "UserNotFoundException";
} catch (PersistenceException e) {
//throw new WebApplicationException(Response.Status.INTERNAL_SERVER_ERROR);
return "WebApplicationException";
}
}
Junit测试方法(String中的版本完美运行)
@Test
public void testUserInfoResponseJSON() throws Exception{
MvcResult result=mockMvc.perform(get("/helloservice/json2?p=103")
.contentType(MediaType.APPLICATION_JSON))
.andExpect(status().isOk())
.andExpect(content().contentTypeCompatibleWith("application/json"))
.andReturn();
String content = result.getResponse().getContentAsString();
assertNotNull(content,"{login name:jbray}");
}
如果需要,继承我的pom.xml

答案 0 :(得分:0)
我详细了解了您的依赖关系和代码,发现您正在使用Glassfish的JSR 353提供程序实现。这些类是org.glassfish.json.JsonObjectBuilderImpl$JsonObjectImpl, org.glassfish.json.JsonStringImpl, and org.glassfish.json.JsonNumberImpl, and javax.json.JsonValue$3 (an anonymous class for the value FALSE)
。
您需要更改以下代码
return Json.createObjectBuilder().add("login name", rs.getString("loginName"));
return Json.createObjectBuilder().add("login name", "shit broke yo!!!");
到
return Json.createObjectBuilder().add("login name", rs.getString("loginName")).build().toString();
return Json.createObjectBuilder().add("login name", "shit broke yo!!!").build().toString();
并将getUserInfoJSON()
方法的返回类型更改为String
。有关JSR 353类的详细说明以及映射到ObjectMapper的信息,请访问https://stackoverflow.com/a/19205116/3530898
