Question

我有问题。我尝试使用angularjs将http发送到我的控制器。

@RequestMapping(value = "/books/manage", method = RequestMethod.POST)
@ResponseBody
public void manageBooks(@RequestBody final BooksDTO dto)
        throws SystemException, IOException {
    System.out.println("DTO WAS SEND!");
    }
}

这里是Angularjs

$http.post($scope.BooksUrl, {
                        'title':Title,
                        'booksUrl':Url,
                        'number':Number
                }).error(function (response) {
                    // error message
                }).then(function(){
                    // success message
                });

标题是

Accept:application/json, text/plain, */*
Accept-Encoding:gzip, deflate
Accept-Language:en-US,en;q=0.8,ru;q=0.6
Connection:keep-alive
Content-Length:72
Content-Type:application/json;charset=UTF-8

但它捕获“HTTP - 415状态。服务器拒绝了此请求，因为请求实体的格式不受所请求方法所请求资源的支持。”我该如何解决？

Answer 1

尝试使用控制器中的以下代码

@RequestMapping(value = "/books/manage", method = RequestMethod.POST,consumes="application/json")

Answer 2

这也可能是由于缺少消息转换器。尝试注册一个（杰克逊在你的情况下）。需要将java对象转换为JSON，这是由JSON消息转换器完成的。如果使用@EnableWebMVC或mvc：annotation-driven标签（在xml配置的情况下）并将jackson添加到类路径中，则会隐式添加MappingJacksonHttpMessageConverter。看看你的pom是否有Jackson依赖，否则添加以下内容：

<dependency>
   <groupId>com.fasterxml.jackson.core</groupId>
   <artifactId>jackson-databind</artifactId>
   <version>2.4.6</version>
</dependency>

Answer 3

我找到了解决方案。问题出在servlet xml：

<tx:annotation-driven/>

应替换为

<mvc:annotation-driven/>

我不知道差异是什么，但它有效（有人可以解释一下吗？）谢谢大家的回答。

Answer 4

我不知道有什么区别，但它有效（有人可以解释一下吗？）谢谢大家的回答。

tx：annotation-driven - 用于启用@Transactional

等事务注释

mvc：annotation-driven - 用于启用Spring MVC注释，如@Controller

这里有一些类似的问题What's the difference between <mvc:annotation-driven /> and <context:annotation-config /> in servlet?

@RequestBody无法正常工作 - HTTP状态415
