idea : springboot访问jsp页面,后台未报错,前台报404

Whitelabel Error Page

This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Not Found, status=404).

/WEB-INF/views/index.jsp

 

TestController .java

@Controller
public class TestController {
    private static final Logger Log = LoggerFactory.getLogger(TestController.class);
        
    @RequestMapping("index")
    public String index(){
       Log.info("Index page .........");
       return "index";
    }
}

MyApplication.java(springboot 启动类)

package com.jqcode;

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class MyApplication {
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		SpringApplication.run(MyApplication.class, args);
	}
}

application.properties

server.port=8080

#设置Tomcat编码
server.tomcat.uri-encoding=UTF-8
#设置视图解析器路径
spring.mvc.view.prefix=/WEB-INF/views/
#设置视图解析器后缀
spring.mvc.view.suffix=.jsp

application.yml

server:
  port: 8080
  tomcat:
    uri-encoding: UTF-8
spring:
  mvc:
    view:
      prefix: /WEB-INF/views/
      suffix: .jsp

仔细检查过该依赖的jar包都已依赖  视图解析的相关配置都已配置 但就是访问不到 /WEB-INF/views/index.jsp页面

查阅了很多资料,idea默认路径是工程的路径 而不是模块的路径。所以我们要手动选择模块路径。
