SpringBoot系列教材 (六)- 基础 - 如何让springboot自动重启


步骤1:必须重启
步骤2:pom.xml
步骤3:重启测试

步骤 1 : 必须重启

目前的Springboot,当发生了任何修改之后,必须关闭后再启动Application类才能够生效,显得略微麻烦。 Springboot提供了热部署的方式,当发现任何类发生了改变,马上通过JVM类加载的方式,加载最新的类到虚拟机中。 这样就不需要重新启动也能看到修改后的效果了

步骤 2 : pom.xml

做法很简单,在pom.xml中新增加一个依赖和一个插件就行了。
依赖:

<dependency>

    <groupId>org.springframework.boot</groupId>

    <artifactId>spring-boot-devtools</artifactId>

    <optional>true</optional> <!-- 这个需要为 true 热部署才有效 -->

</dependency>


插件:

<plugin>

    <groupId>org.springframework.boot</groupId>

    <artifactId>spring-boot-maven-plugin</artifactId>

</plugin>

<?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">

        </dependency>

        <!-- servlet依赖. -->

        <dependency>

              <groupId>javax.servlet</groupId>

              <artifactId>javax.servlet-api</artifactId>

               

        </dependency>

              <dependency>

                     <groupId>javax.servlet</groupId>

                     <artifactId>jstl</artifactId>

              </dependency>

        <!-- tomcat的支持.-->

        <dependency>

               <artifactId>tomcat-embed-jasper</artifactId>

                

        </dependency>    

        <dependency>

            <groupId>org.springframework.boot</groupId>

            <artifactId>spring-boot-devtools</artifactId>

            <optional>true</optional<!-- 这个需要为 true 热部署才有效 -->

        </dependency>

         

    </dependencies>

    <properties>

        <java.version>1.8</java.version>

    </properties>

    <build>

        <plugins>

            <plugin>

                <groupId>org.springframework.boot</groupId>

                <artifactId>spring-boot-maven-plugin</artifactId>

            </plugin>

        </plugins>

    </build>

</project>

步骤 3 : 重启测试

重新启动Application,然后随便修改一下HelloController, 就会如图所示观察到控制台的自动重启现象

重启测试
