一直试图解决这个问题,我确信我的二传手和吸气手都没问题。这是here
的啧啧这是我的错误

这是HelloController
/*

*/
package controller;
import java.net.BindException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.SimpleFormController;
import service.HelloService;
/**

*/
public class HelloController extends SimpleFormController {
public HelloController() {
//Initialize controller properties here or
//in the Web Application Context
setCommandClass(Name.class);
setCommandName("Name");
setSuccessView("helloView");
setFormView("nameView");
}
//Use onSubmit instead of doSubmitAction
//when you need access to the Request, Response, or BindException objects
//@Override
protected ModelAndView onSubmit(
HttpServletRequest request,
HttpServletResponse response,
Object command,
BindException errors) throws Exception {
Name name = (Name) command;
ModelAndView mv = new ModelAndView(getSuccessView());
mv.addObject("helloMessage", HelloService.sayHello(name.getValue()));
return mv;
}
}
最后是Name.java
/*

*/
package controller;
/**

public class Name {
private String value;
public String getValue() {
return value;
}
public void setValue(String value) {
this.value = value;
}
}
如果我需要显示代码的任何其他部分,请告诉我,我现在找了几天但找不到解决方案。
由于
答案 0 :(得分:2)
根据dispatcher-servlet.xml
中的错误,您的setHelloService
课程中不应该有HelloController
方法吗?
哦,是的,我认为这是问题所在,我刚刚查看了您链接的教程,请查看第15点。
