Question

编辑：固定！无需回复

我必须为学校创建一个项目，我无法找到这个不断出现的HTTP错误的解决方案......

我会尝试尽可能缩短代码，而不会忘记任何代码。

我正在使用带有XML配置的Spring MVC：

<?xml version='1.0' encoding='UTF-8' ?>
<beans xmlns="http://www.springframework.org/schema/beans"
   etc..>

<context:component-scan base-package="ui.controller"/> 
<mvc:annotation-driven/>
</beans>

的pom.xml：

  <dependency>
        <groupId>com.fasterxml.jackson.core</groupId>
        <artifactId>jackson-core</artifactId>
        <version>2.7.3</version>
    </dependency>

    <dependency>
        <groupId>com.fasterxml.jackson.core</groupId>
        <artifactId>jackson-annotations</artifactId>
        <version>2.7.3</version>
    </dependency>

    <dependency>
        <groupId>com.fasterxml.jackson.core</groupId>
        <artifactId>jackson-databind</artifactId>
        <version>2.7.3</version>
    </dependency>

休息控制器：

@RestController
@RequestMapping(value = "/rest")
public class ProductRESTController {

private final ProductService service;

public ProductRESTController(@Autowired ProductService service) {
    this.service = service;
}

@RequestMapping(method = RequestMethod.GET, headers = "Accept=application/json")
public List<Product> getProducts() {
    return service.getAllProducts();
}
}

我们必须使用Postman来检查我们的REST控制器的功能，所以我也会发布标题代码：

GET /SchoolProject/rest.htm HTTP/1.1
Host: localhost:8080
Accept: application/json
Cache-Control: no-cache
Postman-Token: 1543765c-b6c0-c82a-6c7d-6e4ce445fa16

我尝试过多次，多次更改代码，但没有任何效果。我一直收到406 HTTP错误：

"The resource identified by this request is only capable of generating responses with characteristics not acceptable according to the request "accept" headers."

即使我做客户端＆amp;服务器端Application / Json ......

请帮忙！

Answer 1

你应该使用＆＃39;产生＆＃39; @RequestMappings上的属性：

@RequestMapping(method = RequestMethod.GET, produces = "application/json")
public List<Product> getProducts() {
    return service.getAllProducts();
}
}

Answer 2

@RequestMapping(value="/getProducts",method = RequestMethod.GET,consumes=MediaType.APPLICATION_JSON_UTF8_VALUE,produces=MediaType.APPLICATION_JSON_UTF8_VALUE)
public List<Product> getProducts() {
    return service.getAllProducts();
}

GET / getProducts

Answer 3

这是你的xml中的内容吗？看看。

    <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation="http://www.springframework.org/schema/mv‌c http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd‌">
