玩转spring boot——MVC应用

如何快速搭建一个MCV程序？

参照spring官方例子：https://spring.io/guides/gs/serving-web-content/

一、spring mvc结合thymeleaf模板

创建maven project后，修改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>com.github.carter659</groupId>
    <artifactId>spring02</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <packaging>jar</packaging>

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.4.2.RELEASE</version>
    </parent>

    <name>spring02</name>
    <url>http://maven.apache.org</url>

    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <java.version>1.8</java.version>
    </properties>

    <dependencies>
        <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>
    </dependencies>

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

pom.xml

添加“MainController.java”这个控制器的类文件：

package com.github.carter659.spring02;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;

@Controller
public class MainController {

    @GetMapping("/")
    public String index(Model model) {
        model.addAttribute("name", "刘冬");
        return "index";
    }

}

修改App.java文件

package com.github.carter659.spring02;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class App {
    public static void main(String[] args) {
        SpringApplication.run(App.class, args);
    }
}

然后在项目中右键进入java build path

添加文件夹“And Folder”

在main目录下添加“resources”文件夹

修改"resources"的“Excluded”：

输入“**”

在src/main/resources下创建“templates”文件夹，并新建一个html文件“index.html”

<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<title>MVC</title>
</head>
<body>
    <p th:text="'Hello, ' + ${name} + '!'" />
</body>
</html>

输入http://localhost:8080 检测是否运行成功：

以上是使用thymeleaf模板做的动态页面，那么，如何在MVC应用中使用静态资源呢？

二、静态资源

在src\main\resources下新建“static”文件夹

并在其文件夹中复制进一张图片文件

修改之前的“index.html”文件，增加img标签

<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<title>MVC</title>
</head>
<body>
    <img alt="ae86" src="img.png" />
    <p th:text="'Hello, ' + ${name} + '!'" />
</body>
</html>
