415将json发送到弹簧控制器时，不支持的介质类型

标签： java json spring jackson type-conversion

我发送带有“Content-Type”的POST http请求 "application/json"到我的控制器

我有以下依赖项：

     <!--JSON-->
    <dependency>
        <groupId>org.codehaus.jackson</groupId>
        <artifactId>jackson-mapper-asl</artifactId>
    </dependency>
    <dependency>
        <groupId>org.codehaus.jackson</groupId>
        <artifactId>jackson-core-asl</artifactId>
    </dependency>

以下控制方法：

    @RequestMapping(value = "sendData.json", method = RequestMethod.POST, consumes = "application/json")
    @ResponseStatus(HttpStatus.NO_CONTENT)
    public void putJsonData(@RequestBody RequestResponseWrapper requestResponseWrapper) {
        ...
    }

RequestResponseWrapper并且所有类都有默认构造函数

我看到以下春季日志：

我花了很多时间来调试spring但我无法理解我的错误。

2 个答案:

答案 0 :(得分：4)

我发现了问题原因

我有两个名称为Sku和SKU的字段，并且设置了相应的方法。

杰克逊不能接受以下命名的混乱

P.S。 spring提供了令人困惑的错误消息

答案 1 :(得分：0)

我还发现错误代码具有误导性，因为当Spring无法将您的@RequestBody类（以下示例中的TheEntity）转换为json时，通常会发生错误代码。 

@PostMapping
public ResponseEntity<KerasModel> createNewEntity(@RequestBody TheEntity theEntity){
    return new ResponseEntity(entityService.createNew(theEntity),HttpStatus.CREATED);
}

您可能需要使用@Json注释所有非@Entity类型的字段。
