Question

我想发送＆＃34;价值＆＃34;从Radio按钮之一到SpringMVC，但我看到了我没想到的问题。我已经阅读了关于我的主题的类似答案，但我还没有在我的问题上找到答案 HTML：

 <form action="addRadio"  method="post" >

            <input type="radio" name="rbn" id="rbn" value="Red"/>Red
            <input type="radio" name="rbn"  value="White"/>White
            <input type="radio" name="rbn"  value="Blue"/>Blue
            <input type="radio" name="rbn"  value="Yellow"/>Yellow

            <input type="submit" value="Submit"/>

    </form>

尝试接受Java：

@Controller
public class testController {
@RequestMapping(name = "/test", method = {RequestMethod.GET, RequestMethod.POST})
public ModelAndView seeTest(){
    ModelAndView m = new ModelAndView();
    m.setViewName("addFabric/testRadio");
    return m;
}
@RequestMapping(name = "/addRadio", method = {RequestMethod.GET, RequestMethod.POST})
public ModelAndView add(@RequestParam(value = "rbn", required = false) String name){
    ModelAndView modelAndView = new ModelAndView();
    System.out.println("Type Radio: "+name);
    modelAndView.setViewName("index");
    return modelAndView;
}

} 我收到了这个错误：

        org.springframework.beans.factory.BeanCreationException: Error creating bean     with name 'requestMappingHandlerMapping'
 defined in class path resource   [org/springframework/boot/autoconfigure/web/WebMvcAutoConfiguration$EnableWebMvcConfiguration.class]:

    public org.springframework.web.servlet.ModelAndView margo.controller.add.testController.seeTest()
    to {[],methods=[GET || POST]}: There is already 'addTestController' bean method

Answer 1

您已将类add中的方法addTestController映射到路径/test。因此，请更改addTestController或testController中的路径。此外，您可能希望坚持Java命名约定并使用大写字母启动类名。

Answer 2

作为@dunni mentioned，还有另一个控制器addTestController，您可以在其中使用重复的方法。

此外，您应该从RequestMethod.POST方法移除seeTest()，并从RequestMethod.GET移除add(...)：

@RequestMapping(name = "/test", method = RequestMethod.GET)
public ModelAndView seeTest(){ ... }

@RequestMapping(name = "/addRadio", method = RequestMethod.POST)
public ModelAndView add(@RequestParam(value = "rbn", required = false) String name){ ... }

这是因为您的表单使用POST方法发送数据，因此无需为GET声明/addRadio资源。同时，只需使用表单GET检索页面即可。

Answer 3

尝试提供@RequestBody以查看Test（）方法

Spring MVC模糊映射。无法映射
