Spring Boot 集成 FreeMarker 详解案例 | 泥瓦匠BYSocket

CREATE DATABASE springbootdb;

DROP TABLE IF EXISTS  `city`;
CREATE TABLE `city` (
  `id` int(10) unsigned NOT NULL AUTO_INCREMENT COMMENT'城市编号',
  `province_id` int(10) unsigned  NOT NULL COMMENT'省份编号',
  `city_name` varchar(25) DEFAULT NULL COMMENT'城市名称',
  `description` varchar(25) DEFAULT NULL COMMENT'描述',
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;

INSERT city VALUES (1 ,1,'温岭市','BYSocket 的家在温岭。');

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

这是我这块的配置，如果需要更多的 FreeMarker 配置，可以查看下面的详解：

spring.freemarker.allow-request-override=false # Set whether HttpServletRequest attributes are allowed to override (hide) controller generated model attributes of the same name.
spring.freemarker.allow-session-override=false # Set whether HttpSession attributes are allowed to override (hide) controller generated model attributes of the same name.
spring.freemarker.cache=false # Enable template caching.
spring.freemarker.charset=UTF-8# Template encoding.
spring.freemarker.check-template-location=true # Check that the templates location exists.
spring.freemarker.content-type=text/html # Content-Type value.
spring.freemarker.enabled=true # Enable MVC view resolution for this technology.
spring.freemarker.expose-request-attributes=false # Set whether all request attributes should be added to the model prior to merging with the template.
spring.freemarker.expose-session-attributes=false # Set whether all HttpSession attributes should be added to the model prior to merging with the template.
spring.freemarker.expose-spring-macro-helpers=true # Set whether to expose a RequestContext for use by Spring's macro library, under the name "springMacroRequestContext".
spring.freemarker.prefer-file-system-access=true # Prefer file system access for template loading. File system access enables hot detection of template changes.
spring.freemarker.prefix=# Prefix that gets prepended to view names when building a URL.
spring.freemarker.request-context-attribute=# Name of the RequestContext attribute for all views.
spring.freemarker.settings.*=# Well-known FreeMarker keys which will be passed to FreeMarker's Configuration.
spring.freemarker.suffix=# Suffix that gets appended to view names when building a URL.
spring.freemarker.template-loader-path=classpath:/templates/ # Comma-separated list of template paths.
spring.freemarker.view-names=# White list of view names that can be resolved.

       model.addAttribute("city", cityService.findCityById(id));
       return "city";
   }
   @RequestMapping(value ="/api/city", method = RequestMethod.GET)
   public String findAllCity(Model model) {
       List<City> cityList = cityService.findAllCity();
       model.addAttribute("cityList",cityList);
       return "cityList";
   }
}
