java Restlet无法处理json

Question

这是我的简单restlet代码：

public class MailServerResource extends ServerResource {

    @Get("json")
    public String getMail() {
        return this.getRequest().getEntityAsText();
    }

    @Post("json")
    public String sendMail() {
        return this.getRequest().getEntityAsText();
    }
}

现在，当我访问此资源并传递此字符串时：

{"employees":[
    {"firstName":"John", "lastName":"Doe"},
    {"firstName":"Anna", "lastName":"Smith"},
    {"firstName":"Peter", "lastName":"Jones"}
]}

它抛出：

The server is refusing to service the request because the entity of the request is in a format not supported by the requested resource for the requested method

Answer 1

你能试试这个语法吗

@Post("json")
public String sendMail(String json) {
    return json;
}

带注释的方法可以包含一个表示请求实体（如果有）的参数

注意：顺便说一句，Get请求没有有效负载。本说明没有任何含义：

this.getRequest().getEntityAsText()
