我正在开发 RESTful 服务。
我无法将 JSON 数据发布到控制器。
我正在使用以下依赖项：
我也尝试过：
- Spring 3.2.3.RELEASE 与 Jackson 1.9.9
- Spring 3.1.1.RELEASE w/ Jackson 1.9.9
正如这里所建议的将 JSON 发布到 Spring MVC 控制器返回 400 错误请求 https://stackoverflow.com/questions/22869403/posting-json-to-spring-mvc-controller-returns-400-bad-request
我也输入了 MessageConverters，
<mvc:annotation-driven>
<mvc:message-converters>
<bean class="org.springframework.http.converter.StringHttpMessageConverter"/>
<bean class="org.springframework.http.converter.ResourceHttpMessageConverter"/>
<bean class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter"/>
</mvc:message-converters>
</mvc:annotation-driven>
控制器
@Controller
@RequestMapping(value="/todo", consumes="application/json", produces="application/json")
//@RequestMapping(value="/todo", consumes="text/plain", produces="application/json")
public class TodoRestService {
Logger logger = LoggerFactory.getLogger(TodoService.class);
@Autowired
private TodoService todoService;
@RequestMapping(value="/{id}", method= RequestMethod.GET)
@ResponseBody public Todo find(@PathVariable("id") Long id) {
Todo todo = todoService.find(id);
return todo;
}
@RequestMapping(method=RequestMethod.POST)
@ResponseBody public Todo create(@RequestBody Todo todo) {
//public Todo create(@RequestBody String todo) {
//public Todo create(@RequestParam("todo") String todo) {
System.out.println(todo);
todoService.create(newTodo);
return newTodo;
}
}
POJO
public class TODO {
private String firstName;
private String lastName;
//getter setters
}
我正在使用邮递员来发布 JSON
我已将 Content-Type 设置为 application/json
表单数据-----
名称 = 待办事项
值 = {"firstName":"nilam","lastName":"naik"}
方法=POST
我收到 400 错误请求。
但是如果我将 @RequestBody 注释的参数的数据类型从 TODO 更改为 String 那么
我得到类似的东西，
------WebKitFormBoundaryu6banLlTPiPudsBB
Content-Disposition: form-data; name="todo"
{"firstName":"nilam","lastName":"naik"}
------WebKitFormBoundaryu6banLlTPiPudsBB--
我的类路径上也有 Jackson。
如果我将属性 Consumers 从 application/json 更改为 text/plain 并且
@RequestBody String todo 然后我得到，
{"firstName":"nilam","lastName":"naik"}
但我不想手动将字符串转换为 Java 对象。但我不明白为什么 @RequestBody 无法将我的 JSON 数据转换为 Java 对象。
