本篇博文將和大家一起使用Spring Boot 2.0 和FreeMarker 模板引擎整合實戰。
1. 創建新的項目
2. 填寫項目配置信息
3. 勾選web 模塊
4. 勾選freemarker模板引擎模塊
5.填寫項目名稱和項目保存路徑
6. 修改POM文件,添加Freemarker 項目依賴
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.xingyun</groupId> <artifactId>spring-boot-with-freemarker-sample</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>jar</packaging> <name>spring-boot-with-freemarker-sample</name> <description>Demo project for Spring Boot</description> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.0.1.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> <java.version>1.8</java.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-freemarker</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project>
7. 配置applicaiton.properties
# 設定ftl文件路徑
spring.freemarker.template-loader-path=classpath:/templates
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=false
spring.freemarker.expose-session-attributes=false
spring.freemarker.request-context-attribute=request
spring.freemarker.suffix=.ftl
Tips: 其實我試了下，把.ftl 換成.jsp ，創建JSP 文件也是可以的。
8. 創建文件夾和ftl格式文件
index.ftl
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> </head> <body> this is index page </body> </html>
welcome.ftl
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> </head> <body> this is welcome page </body> </html>
9. 創建 Controller
package com.xingyun.springbootwithfreemarkersample.controller; import org.springframework.stereotype.Controller; import org.springframework.ui.ModelMap; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.RequestBody; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; @Controller public class HomeController { @RequestMapping(value = "/") public String index(){ return "views/index"; } @RequestMapping(value = "/welcome") public String home(){ return "views/welcome"; } }
Tips: 由於要返回模板頁面文件，所以我們只能使用@Controller 而不可以使用@RestController
