如何在@RestController中映射多个bean ?
我正在使用spring-web-4.3.8.RELEASE.jar
我尝试了一切: @RequestParam @RequestBody,@ RequestAttribute,@ RequestPart 但没有任何作用......
package com.example.demo;
import org.springframework.http.MediaType;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class RestService {
@RequestMapping(value = "demo", method = RequestMethod.POST, consumes = MediaType.APPLICATION_FORM_URLENCODED_VALUE)
public Object[] demo(Foo foo, Bar bar) {
return new Object[]{foo, bar};
}
public static class Bar {
public Long id;
public String bar;
}
public static class Foo {
public Long id;
public String foo;
}
}
我的(已编码)有效负载是:
富=%7B%22id%22%3A123%2C%22foo%22%3A%22foo1%22%7D&安培;栏=%7B%22id%22%3A456%2C%22bar%22%3A%22bar1%22 %7D
解码的有效负载:
富= { “ID”:123, “foo” 的: “foo1”}&安培;栏= { “ID”:456, “酒吧”: “BAR1”}
请求标题:
内容类型:application / x-www-form-urlencoded
使用上面的代码,它返回:
[{ “ID”:空, “foo” 的日期null},{ “ID”:NULL, “酒吧”:空}]
但我想要的是:
[{ “ID”:123, “foo” 的: “foo1”},{ “ID”:456, “酒吧”: “BAR1”}]

您正在RestController中创建静态内部类。 Spring无法使用上述bean自动映射接收到的请求中的属性。请在单独的包或外部控制器中定义您的bean。然后,您将能够使用@RequestBody映射它。
@RestController
public class RestService {
@RequestMapping(value = "demo", method = RequestMethod.POST, consumes = MediaType.APPLICATION_FORM_URLENCODED_VALUE)
public Object[] demo(@RequestBody FooBar foobar) {
// your custom work
}
}
public class Bar {
public Long id;
public String bar;
}
public class Foo {
public Long id;
public String foo;
}
// created wrapper as @RequestBody can be used only with one argument.
public class FooBar {
private Foo foo;
private Bar bar;
}
请参阅requestBody with multiple beans
还要确保请求参数名称与bean的属性匹配。(即Foo和Bar)。
