我有个问题。我尝试使用 angularjs 将 http post 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 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。服务器拒绝此请求，因为请求实体的格式不受所请求方法的请求资源支持。” 我该如何解决？

尝试在您的控制器中使用以下代码

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

这也可能是由于缺少消息转换器。尝试注册一个（在您的情况下为杰克逊）。需要将 java 对象转换为 JSON，这是由 JSON 消息转换器完成的。如果如果使用 @EnableWebMVC 或 mvc:annotation-driven 标记（在 xml 配置的情况下）并且 jackson 被添加到您的类路径中，则 MappingJacksonHttpMessageConverter 被隐式​​添加。查看您的 pom 是否具有 Jackson 依赖项，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>

我想出了解决方案。问题出在 servlet xml 中：

<tx:annotation-driven/>

应该替换为

<mvc:annotation-driven/>

我不知道有什么区别，但它有效（有人可以解释吗？）谢谢大家的回答。

tx:annotation-driven - 用于启用事务注释，如@Transactional

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

这里有一些类似的问题servlet 中的 <mvc:annotation-driven /> 和 <context:annotation-config /> 有什么区别？
