SpringBoot入门环境搭建，maven构建，Intellij IDEA 2016.2

springboot springboot 评论

Intellij IDEA工具下搭建SpringBoot入门程序使用maven

环境准备

  • Intellij IDEA 2016.2
  • maven 3.0.5
  • SpringBoot 1.5.8

步骤

一、新建项目

file->new->project
创建项目选择maven如下图

点击next
如图填入自己项目的信息，由于是创建的maven项目，所以此处填写maven需要的字段信息，具体见途中说明

点击next
这一步填写项目的名称和存储的路径

点击finish创建成功
到这一步一个简单的maven工程就创建完成了。

二、添加springboot支持

pom.xml文件中增加配置

            <artifactId>spring-boot-maven-plugin</artifactId>
            <configuration>
                <fork>true</fork>
            </configuration>
        </plugin>
    </plugins>
</build>

由于最终要打包成jar格式所以pom.xml中还需增加配置

<groupId>com.wzk</groupId>
<artifactId>spring02</artifactId>
<version>1.0-SNAPSHOT</version>
<packaging>jar</packaging>

注意:jar参数的值为:jar

三、编写测试代码

创建类如下，SpringBoot的启动类，如果不做任何配置，默认启动的容器是tomcat

package com.wzk.ms;

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


@SpringBootApplication
public class SpringbootApplication {

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

再写一个自己的controller类，输入经典的helloworld

package com.wzk.ms;

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

@RestController
public class HelloWorldController {
    @RequestMapping("/hello")
    public String index() {
        String test = "Hello";
        String test1 = " world";
        String returnStr = test + test1;
        return returnStr;
    }
}

四、启动测试

  • SpringbootApplication是一个含有main方法的java程序，所以直接运行
  • 浏览器输入http://localhost:8080/hello
    因为默认是tomcat所以端口默认8080，返回Hello world.

五、配置

修改springboot的配置很简单，直接修改resource下的application.properties文件即可。
如修改访问端口为8081，添加配置
server.port=8081

tomcat的其他配置可以参考
server.port=8081

#server.address= # bind to a specific NIC
#server.session-timeout= # session timeout in seconds
#the context path, defaults to '/'
#server.context-path=/spring-boot
#server.servlet-path= # the servlet path, defaults to '/'
#server.tomcat.access-log-pattern= # log pattern of the access log
#server.tomcat.access-log-enabled=false # is access logging enabled
#server.tomcat.protocol-header=x-forwarded-proto # ssl forward headers
#server.tomcat.remote-ip-header=x-forwarded-for
#server.tomcat.basedir=/tmp # base dir (usually not needed, defaults to tmp)
#server.tomcat.background-processor-delay=30; # in seconds
#server.tomcat.max-threads = 0 # number of threads in protocol handler
#server.tomcat.uri-encoding = UTF-8 # character encoding to use for URL decoding

六、打包成jar

打包成可运行的jar
intelliJ打开命令行，运行mvn clean package即可
默认输出到target目录下，然后输入java -jar xxx.jar即可启动
关闭命令行窗口即关闭了容器
