Spring Boot项目Circular view path问题解决

使用Spring Boot创建Spring MVC项目,访问url请求出现问题:Circular view path

1、问题描述

控制台打印:

javax.servlet.ServletException: Circular view path [greeting]: would dispatch back to the current handler URL [/greeting] again. Check your ViewResolver setup! (Hint: This may be the result of an unspecified view, due to default view name generation.)

浏览器访问:

2、项目代码

(1)Spring MVC的controller

 1 package com.hello.web;
 2 
 3 import org.springframework.stereotype.Controller;
 4 import org.springframework.ui.Model;
 5 import org.springframework.web.bind.annotation.RequestMapping;
 6 import org.springframework.web.bind.annotation.RequestParam;
 7 
 8 @Controller
 9 public class GreetingController {
10     @RequestMapping("/greeting")
11     public String greeting(@RequestParam(value="name",required=false,defaultValue="World")String name, Model model) {
12         model.addAttribute("name", name);
13         return "greeting";
14     }
15 }

(2)页面代码

使用 thymeleaf模板框架,负责服务端渲染html页面

 1 <!DOCTYPE html>
 2 <html xmlns:th="http://www.thymeleaf.org">
 3 <head>
 4 <title>Spring Boot thymeleaf 应用</title>
 5 <meta http-equiv="Content-Type" content="text/html;charset=UTF-8">
 6 </head>
 7 <body>
 8     <p th:text="'hello, '+${name}+'!'" />
 9 </body>
10 </html>

3、解决方法

在 项目的 pom.xml中添加 thymeleaf 的 spring boot starter

1 <dependency>
2     <groupId>org.springframework.boot</groupId>
3     <artifactId>spring-boot-starter-thymeleaf</artifactId>
4 </dependency>

4、问题解决

再次通过浏览器地址栏,访问: http://localhost:8080/greeting?name=zhangsan
