springboot-freemarker 模板引擎(第六篇)

FreeMarker是一个用Java语言编写的模板引擎，它基于模板来生成文本输出。FreeMarker与Web容器无关，即在Web运行时，它并不知道Servlet或HTTP。它不仅可以用作表现层的实现技术，而且还可以用于生成XML，JSP或Java 等。

创建项目

创建项目完成如下：

在pom.xml文件中引入freemark依赖包

<?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.example.springboot</groupId>
    <artifactId>springboot-freemarker</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <packaging>jar</packaging>

    <name>springboot-freemarker</name>
    <description>Demo project for Spring Boot</description>

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.5.12.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>1.7</java.version>
    </properties>

    <dependencies>

        <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>
        <!--引入freemark依赖包-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-freemarker</artifactId>
        </dependency>
    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>


</project>

在application.properties配置文件添加freemark配置

#修改server端口
#server.port=8085
#server.context-path=/springdemo

##freemarker配置信息
spring.freemarker.allow-request-override=false
spring.freemarker.cache=true
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
#spring.freemarker.prefix=
#spring.freemarker.request-context-attribute=
#spring.freemarker.settings.*=
#spring.freemarker.suffix=.ftl
#spring.freemarker.template-loader-path=classpath:/templates/#comma-separatedlist
#spring.freemarker.view-names= #whitelistofviewnamesthatcanberesolved


#添加jsp配置
# 页面默认前缀目录
spring.mvc.view.prefix=/WEB-INF/jsp/
# 响应页面默认后缀
spring.mvc.view.suffix=.jsp
# 自定义属性，可以在Controller中读取
application.hello=Hello Angel From application

编写模板controller类

package com.example.springboot.freemarker.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import java.util.Map;

@Controller
@RequestMapping("/freemarker")
public class FreemarkerConroller {

   @RequestMapping("/index")
   public String web(Map<String, Object> model) {
      model.put("message","freemar测试");
      model.put("content","测试freemar创建及如何取值");
      // 返回的内容就是templetes下面文件的名称
      return "index";
   }
}

编写模板文件

在 src\main\resources\templates\index.ftl 创建index.ftl模板文件。

<!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>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
   message: ${message}</br>
</body>
</html>

启动服务测试

通过页面访问测试：http://localhost:8080//freemarker/index

以上表示freemark创建成功！
