Spring boot 梳理

开发环境中关闭缓存

spring:
    thymeleaf:
        cache: false
    freemarker:
        cache: false

Spring boot 集成 freemarker

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-freemarker</artifactId>
        </dependency>

oa/src/main/resources/templates/hello.ftl

<!DOCTYPE html>  
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:th="http://www.thymeleaf.org"  
      xmlns:sec="http://www.thymeleaf.org/thymeleaf-extras-springsecurity3">  
    <head>  
        <title>Hello World!</title>  
    </head>  
    <body>
       <center>
       OK
       </center>
    </body>  
</html>

@Controller

@Controller
@RequestMapping("/fruit")
public class FruitController {
    @RequestMapping(value="{fruitName}", method = RequestMethod.GET)
    public String getFruit(@PathVariable String fruitName, ModelMap model) {

        //Fruit fruit = new Fruit(fruitName, 1000);
        HashMap<String,String> fruit=new HashMap<String,String>();
        fruit.put("fruit", "fruit");
        model.addAttribute("model", fruit);
        
        return "hello";

    }
}

访问
1. http://localhost:8080/fruit/a
2. 显示 OK

可以设置freemarker属性

application.properties

spring.freemarker.allow-request-override=false
spring.freemarker.cache=false
spring.freemarker.check-template-location=true
spring.freemarker.charset=UTF-8
spring.freemarker.content-type=text/html
spring.freemarker.expose-request-attributes=false
spring.freemarker.expose-session-attributes=false
spring.freemarker.expose-spring-macro-helpers=false
