freemarker:

freemarker所需要依赖:

<!-- 添加freemarker模版的依赖 -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-freemarker</artifactId>
        </dependency>

application.properties中freemarker的配置:

## Freemarker 配置
spring.freemarker.template-loader-path=classpath:/templates/
spring.freemarker.cache=false
spring.freemarker.suffix=.ftl
spring.freemarker.charset=UTF-8
spring.freemarker.check-template-location=true
spring.freemarker.content-type=text/html
spring.freemarker.expose-request-attributes=false
spring.freemarker.expose-session-attributes=false
spring.freemarker.request-context-attribute=request  

 

Controller中的配置:

 

 

 所需要的页面:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
欢迎!${name}
</body>
</html>

  

springboot中运行时报错是如何跳转到错误页面:

package com.example.demo.exception;

import org.springframework.web.bind.annotation.ControllerAdvice;
import org.springframework.web.bind.annotation.ResponseBody;

import java.util.HashMap;
import java.util.Map;

@ControllerAdvice   //所有Controller运行都会进过这个
public class ExceptionHandler {

  //如果报错执行这个方法
 @org.springframework.web.bind.annotation.ExceptionHandler(RuntimeException.class) 
 @ResponseBody
 public Map<String,Object> ExceptionHandler(){
   Map<String,Object> map = new HashMap<>();
   map.put("error:","500");
   map.put("msg:","頁面報錯了,請稍後,在重試!!1");
   return map;  
   }
 }
