是。我知道这是熟悉的问题。我已经研究过其他解决方案,他们没有帮助我。我正在尝试使用Spring 4,Hibernate 5,My Sql和Angular JS 1.x构建Spring MVC应用程序
问题:如图所示,当我运行应用程序时,它按预期解析为index.jsp文件,然后输入“http://localhost:8080/TimeLee/user/test
”以获取网页'adduser。 html'。 Boom,它会抛出错误'在DispatcherServlet中找到名为'mvc-dispatcher '的带有URI [/TimeLee/WEB-INF/views/adduser.html]的HTTP请求的映射。我检查了控制器映射,一切看起来都不错。
UserController中:
package com.timelee.users.controllers;
import org.springframework.beans.factory.annotation.Autowired;
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.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.servlet.ModelAndView;
import com.timelee.users.model.User;
import com.timelee.users.services.UserService;
@RestController
@RequestMapping("/user")
public class UserController
{
@Autowired
private UserService userService;
@RequestMapping(value="/adduser",method=RequestMethod.POST)
public void saveUser(@RequestBody User user)
{
userService.saveUser(user);
}
@RequestMapping(value="/getuser",method=RequestMethod.GET)
public @ResponseBody User getUser(@RequestParam("userId") String userId)
{
return userService.getUser(userId);
}
@RequestMapping(value="/test",method=RequestMethod.GET)
public ModelAndView test()
{
ModelAndView modelAndView=new ModelAndView("adduser");
return modelAndView;
}
@RequestMapping(value="/test2",method=RequestMethod.GET)
public String test2()
{
return "adduser";
}
}

在<mvc:default-servlet-handler/>
文件中添加spring-mvc-config.xml
。清理项目并重建它。这可以解决您的问题。
答案 1 :(得分:1)
我想尝试添加spring-mvc-config.xml
。希望这对你有用。其他的东西看起来不错。
<mvc:annotation-driven />
<mvc:default-servlet-handler/>
接下来尝试将这些代码添加到web.xml
文件的顶部。在你的情况下它似乎有所不同。
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
version="3.1">
</web-app>
如果它对您不起作用,请按照我的链接查看差异web.xml以及application-context.xml和dispatcher-servlet.xml
答案 2 :(得分:0)
First of all i want to know that is adduser is a jap or HTML file? If yes than use simple return for it.
Second is you create adduser
post method in your controller, right? Add adduser
get method in controller.
Like
@requestmapping(value="adduser",requestmethod.GET)
public String adduser(){
Return // return page name
}
答案 3 :(得分:0)
首先,adduser是jap
还是HTML
文件?如果HTML然后使用简单的返回它。
其次,您的控制器中是否创建了adduser
POST
方法?在控制器中添加adduser
GET
方法。
像:
@requestmapping(value="adduser",requestmethod.GET)
public String adduser(){
Return // return page name
}
此处,404错误仅显示adduser.html
文件夹中没有adduser.jsp
或webinf
,或者您放置了所有jap/HTML
个文件。
