SpringBoot的第一个web项目

这一节主要是讲springboot搭建简单的web项目。

首先pom文件新增spring-boot-starter-web依赖，pom文件如下所示

<?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.dalaoyang</groupId>
    <artifactId>springboot_web</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <packaging>jar</packaging>

    <name>springboot_web</name>
    <description>springboot_web</description>

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.5.10.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>1.8</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-devtools</artifactId>
            <scope>runtime</scope>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
    </dependencies>

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


</project>

然后在项目内新建IndexController，代码如下

package com.dalaoyang.controller;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * @author dalaoyang
 * @Description
 * @project springboot_learn
 * @package com.dalaoyang.controller
 * @email 397600342@qq.com
 * @date 2018/3/13
 */
@RestController
public class IndexController {

    @RequestMapping("/")
    public String index(){
        return "hi dalaoyang";
    }
}

启动类SpringbootWebApplication代码如下

package com.dalaoyang;

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);
    }
}

配置文件如下

##设置端口号
server.port=8888

##springboot项目默认访问是/ 默认不配置下面属性的话 可以直接通过http://ip:port/可以访问index
##如果在配置文件中增加如下配置 则访问时需要访问http://ip:port/dalaoyang
server.context-path=/dalaoyang

就这样一个简单的springboot web项目搭建完成。

然后启动项目 访问http://localhost:8888/dalaoyang/如下图所示
