spring boot 1.5.4入門實例詳解

1.設定maven檔案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.檔案結構（static/templates/application.properties/logback.xml的名稱都是約定好了的，只可以使用某幾個名稱，具體參考spring boot官方文檔，下面的名稱是其中一種配置方式）

#3.建立啟動類別（放在頂層，子層（下層資料夾）的類別方可被掃描注入）

@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類別的下層目錄中）

@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.建立網頁模板login.ftl(freemarker必須使用ftl後綴，被這個坑了好久！js/css啥的都放在對應資料夾下，注意訪問路徑中不帶/static,也被這個坑好久了！ msg=Ladies and gentleman,Welcome!

 

#7.啟動運行

瀏覽器中訪問：http://localhost:8080/common/login

#8.部署

mvn package 打個套件

java -jar xxx.jar 執行這個套件即可
