Spring Boot使用模板引擎

springboot使用thymeleaf

1、加入spring-boot-starter-thymeleaf依赖

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

2、在配置文件中关闭thymeleaf缓存
//开发过程中建议关闭cache
spring.thymeleaf.cache=false

3、新建模板html，路径放在src/main/resources/templates/下

4、新建模板controller类，使用@Controller注解，返回String或者ModelAndView值，该值指向templates目录下文件的路径

@Controller
@RequestMapping("/thymeleaf")
public class ThymeleafController {

    @RequestMapping("/hello0")
    public String hello0(){
        return "thymeleaf";
    }

    @RequestMapping("/hello1")
    public String hello1(Map<String, Object> map){
        map.put("name", "Cay");
        return "thymeleaf";
    }

    @RequestMapping("/hello2")
    public ModelAndView hello2(){
        ModelAndView mv = new ModelAndView();
        mv.addObject("name", "Amy");
        mv.setViewName("thymeleaf");
        return mv;
    }

}

在spring-boot中使用freemarker

1、加入spring-boot-starter-freemarker依赖

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

2、在配置文件中关闭freemarker缓存
spring.freemarker.cache=false

3、新建模板ftl，路径放在src/main/resources/templates/下

4、新建模板controller类，使用@Controller注解，返回String或者ModelAndView值，该值指向templates目录下文件的路径

@Controller
@RequestMapping("/freemarker")
public class FreemarkerController {
 
	@RequestMapping("/hello0")
	public String hello0(){
		return "freemarker";
	}
	
	@RequestMapping("/hello1")
	public String hello1(Map<String, Object> map){
		map.put("name", "Cay");
		return "freemarker";
	}
	
	@RequestMapping("/hello2")
	public ModelAndView hello2(){
		ModelAndView mv = new ModelAndView();
		mv.addObject("name", "Amy");
		mv.setViewName("freemarker");
		return mv;
	}
}

应用程序的application.properties/yml/yaml配置文件

server:
  port: 8081 #修改默认的端口号，默认为8080
  context-path: /springboot #修改默认的contextPath，默认为/
 
spring:
  datasource:
    driver-class-name: com.mysql.jdbc.Driver
    url: jdbc:mysql:///springboot
    username: root
    password: admin
    #springboot支持c3p0，dbcp，如果需要使用其他的数据库连接池，指定type
    # type: 其他的使用指定的dataSource， 比如druid
    
  jpa:
    database: MYSQL
    show-sql: true
 
    hibernate:
      ddl-auto: update
      naming:
        strategy: org.hibernate.cfg.ImprovedNamingStrategy
    properties:
      hibernate.dialect: org.hibernate.dialect.MySQL5Dialect
 
  thymeleaf:
    cache: false #开发过程中建议关闭cache
    #encoding: UTF-8 #thymeleaf编码
    #suffix: .html # thymeleaf后缀
    #content-type: text/html #格式
    
  freemarker:
    cache: false
    #charset: UTF-8
    #suffix: .ftl
    #content-type: text/html

freemarker.ftl文件
