Spring Boot + Thymeleaf 创建web项目
生活随笔
收集整理的這篇文章主要介紹了
Spring Boot + Thymeleaf 创建web项目
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
本篇文章將引導你創建一個簡單的Spring Boot web程序示例，涉及到的組件有：嵌入的Tomcat + Thymeleaf 模板引擎，可執行的 JAR 文件包。
開發工具：
1.Spring Boot?1.5.3.RELEASE
2.Spring 4.3.8.RELEASE
3.Thymeleaf 2.1.5.RELEASE
4.Tomcat Embed 8.5.14
5.Maven 3
6.Java 8
1.創建項目
eclipse -- File -- New -- Maven Project
2.項目的目錄結構如下所示：
手動創建如下的文件夾及文件
3.項目依賴 pom.xml
spring-boot-starter-thymeleaf 這個依賴包將為你提供一切需要的東西來開發一個? Spring + Thymeleaf 程序
pom.xml 文件
<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>org.thinkingingis</groupId><artifactId>spring-boot-web-thymeleaf</artifactId><version>0.0.1-SNAPSHOT</version><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>1.5.3.RELEASE</version></parent><properties><java.version>1.8</java.version></properties><dependencies><!-- 核心依賴 --><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-thymeleaf</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-devtools</artifactId><optional>true</optional></dependency><!-- bootstrap 依賴--><dependency><groupId>org.webjars</groupId><artifactId>bootstrap</artifactId><version>3.3.7</version></dependency></dependencies><build><plugins><!-- macOS 使用如下plugin 這是告訴可執行的jar文件位置，具體情況視你jdk的安裝位置而定--><plugin><artifactId>maven-compiler-plugin</artifactId><version>3.3</version><configuration><fork>true</fork><executable>/Library/Java/JavaVirtualMachines/jdk1.8.0_131.jdk/Contents/Home/bin/java</executable></configuration></plugin><!--windows 系統 使用如下plugin --><!-- <plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId></plugin>--></plugins></build></project>顯示項目的依賴：在終端輸入mvn dependency: tree

4.Spring Boot
4.1添加@SpringBootApplication注解，運行這個類完成spring boot web程序的啟動。
package org.thinkingingis;import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication;@SpringBootApplication public class SpringBootWebApplication {public static void main(String[] args){SpringApplication.run(SpringBootWebApplication.class, args);}}4.2 添加controller類 WelcomeController.java package org.thinkingingis;import java.util.Map;import org.springframework.beans.factory.annotation.Value; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping;@Controller public class WelcomeController {@Value("${welcome.message:test}")private String message = "Hello ThinkingInGIS";@RequestMapping("/")public String welcome(Map<String, Object> model){model.put("message", this.message);return "welcome";}}5. 添加thymeleaf 資源5.1將thymeleaf模板文件存放在 src/main/resources/templates/ 下
welcome.html
application.properties
6. 啟動
6.1進入項目目錄下：/Users/gisboy/Documents/workspace/spring-boot-web-thymeleaf
6.2輸入? mvn spring-boot:run
$ mvn spring-boot:run. ____ _ __ _ _/\\ / ___'_ __ _ _(_)_ __ __ _ \ \ \ \ ( ( )\___ | '_ | '_| | '_ \/ _` | \ \ \ \\\/ ___)| |_)| | | | | || (_| | ) ) ) )' |____| .__|_| |_|_| |_\__, | / / / /=========|_|==============|___/=/_/_/_/:: Spring Boot :: (v1.5.3.RELEASE) 出現 BUILD SUCCESS? 表示成功6.3訪問 http://localhost:8080
至此，一個簡單的spring boot + thymeleaf 程序 就搭建好了。
