1.配置maven文件pom.xml
1.配置maven文件pom.xml
<?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.hdwang</groupid> <artifactid>spring-boot-test</artifactid> <version>1.0-snapshot</version> <name>spring-boot-test</name> <description>project for test spring boot</description> <properties> <project.build.sourceencoding>utf-8</project.build.sourceencoding> <java.version>1.8</java.version> </properties> <!-- inherit defaults from spring boot --> <parent> <groupid>org.springframework.boot</groupid> <artifactid>spring-boot-starter-parent</artifactid> <version>1.5.4.release</version> <relativepath/> </parent> <dependencies> <!-- add typical dependencies for a web application --> <dependency> <groupid>org.springframework.boot</groupid> <artifactid>spring-boot-starter-web</artifactid> </dependency> <dependency> <groupid>org.springframework.boot</groupid> <artifactid>spring-boot-starter-freemarker</artifactid> </dependency> <!-- auto redeploy --> <dependency> <groupid>org.springframework.boot</groupid> <artifactid>spring-boot-devtools</artifactid> <optional>true</optional> </dependency> <!-- package as an executable jar --> <build> <plugins> <plugin> <groupid>org.springframework.boot</groupid> <artifactid>spring-boot-maven-plugin</artifactid> </plugin> </plugins> </build> </project>
2.文件结构(static/templates/application.properties/logback.xml的名称都是约定好了的,只可以使用某几个名称,具体参考spring boot官方文档,下面的名称是其中一种配置方式)
3.建立启动类(放在顶层,子层(下级文件夹)的类方可被扫描注入)
@springbootapplication public class application { /** * main function * @param args params */ public static void main(string[] args){ springapplication.run(application.class,args); } }
4.建立controller(在application类的下级目录中)
@controller @requestmapping("/common") public class common { @value("${msg:welcome!}") private string msg; /** * get a page * @return a page with name called return value */ @requestmapping("login") public string getloginpage(modelmap map){ map.put("welcomemsg",this.msg); return "login"; } }
5.建立网页模板login.ftl(freemarker必须使用ftl后缀,被这个坑了好久!js/css啥的都放在相应文件夹下,注意访问路径中不带/static,也被这个坑了好久!)
<!doctype html> <html> <head> <meta charset="utf-8" /> <title>login</title> <link href="/css/home.css" rel="external nofollow" rel="stylesheet" type="text/css" /> <script type="text/javascript" src="/js/jquery-2.0.3.min.js"></script> <script type="text/javascript" src="/js/home.js"></script> </head> <body> <h1>login page</h1> <h2>${welcomemsg}</h2> <form> <div> <label>用户名:<input type="text" id="username"/></label> </div> <div> <label>密码:<input type="password"/></label> </div> <div> <input type="submit" value="提交"/> <input type="reset" value="重置" /> </div> </form> </body> </html>
6.应用配置文件编写
新建application.properties文件并添加以下内容
msg=ladies and gentleman,welcome!
7.启动运行
浏览器中访问:
8.部署
mvn package 打个包
java -jar xxx.jar 运行这个包即可
