我收到主题行中提到的异常。能否请您解释一下什么是错的:spring客户端发送的请求在语法上不正确()问题
package mvc;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;
@Controller
@RequestMapping("/req")
public class Req {
@RequestMapping(method = RequestMethod.GET)
@ResponseBody
public String get(@RequestBody String body) {
return body;
}
}
用SpringMVC-servlet.xml中
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

<!--It tells the Spring framework to look for annotations and then do appropriate dependency injections.-->

<!--used to provide base package to scan components-->

<mvc:annotation-driven>
<mvc:message-converters>
<bean class="org.springframework.http.converter.StringHttpMessageConverter"/>
</mvc:message-converters>
</mvc:annotation-driven>
</beans>
当我试图访问http://localhost:8080/SpringMVC/req
HTTP Status 400 -
type Status report
message
description The request sent by the client was syntactically incorrect().
Apache Tomcat/7.0.16
请帮我弄明白原因问题。
谢谢, 的Sandip
你不是在GET请求体发送任何([它并没有多大意义,反正](http://stackoverflow.com/q/978061/1240557)),所以Spring不能通过'@ RequestBody'绑定任何东西。你期望在你的控制器代码的'body'值中看到什么? – kryger
我想检查RequestBody的工作方式。 你的意思是RequestBody注解不适用于GET? 我会尝试POST方法。 –
使用POST而不是GET。而现在,您并未在HTTP请求正文中提供任何数据。 – John
