springboot 常用配置之多环境配置

在上一课中我们通过idea工具没有做任何配置就构建了一个springboot项目,并且已经成功启动了,但我们都很清楚这些都远远不能达到我们实际项目的需求,比如我们要引入我们自己的redis配置、mysql配置等,应该如何处理呢?在spring mvc中我们都是通过spring.xml相关文件配置,在springboot中这些都已经不存在了,我们应该怎样配置呢?别急,马上为大家揭晓谜底,跟着我一起来吧!

NO1.我们在做项目的时候是不是都会区分很多环境呢?比如开发环境、测试环境、生产环境等,那么第一步我将先带大家配置好各个环境;

1.首先打开我们项目的pom.xml文件加入以下内容:

<build>
   <finalName>${project.artifactId}-${project.version}</finalName>
   <plugins>

      <plugin>
         <groupId>org.springframework.boot</groupId>
         <artifactId>spring-boot-maven-plugin</artifactId>
         <executions>
            <execution>
               <goals>
                  <goal>repackage</goal>
               </goals>
            </execution>
         </executions>
      </plugin>

      <plugin>
         <groupId>org.apache.maven.plugins</groupId>
         <artifactId>maven-compiler-plugin</artifactId>
         <version>3.3</version>
         <configuration>
            <source>1.8</source>
            <target>1.8</target>
            <encoding>utf8</encoding>
         </configuration>
      </plugin>

   </plugins>

   <filters>
      <filter>src/main/resources/application-${filter-resource-name}.properties</filter>
   </filters>
   <resources>
      <resource>
         <directory>src/main/resources</directory>
         <filtering>true</filtering>
         <excludes>
            <exclude>filters/*</exclude>
            <exclude>filters/*</exclude>
            <exclude>application-dev.properties</exclude>
            <exclude>application-test.properties</exclude>
            <exclude>application-alpha.properties</exclude>
            <exclude>application-prod.properties</exclude>
         </excludes>
      </resource>
      <resource>
         <directory>src/main/resources</directory>
         <filtering>true</filtering>
         <includes>
            <include>application-${filter-resource-name}.properties</include>
         </includes>
      </resource>
   </resources>
</build>

<profiles>
   <profile>
      <id>dev</id>
      <activation>
         <activeByDefault>true</activeByDefault>
      </activation>
      <properties>
         <filter-resource-name>dev</filter-resource-name>
      </properties>
   </profile>

   <profile>
      <id>test</id>
      <properties>
         <filter-resource-name>test</filter-resource-name>
      </properties>
   </profile>

   <profile>
      <id>alpha</id>
      <properties>
         <filter-resource-name>alpha</filter-resource-name>
      </properties>
   </profile>

   <profile>
      <id>prod</id>
      <properties>
         <filter-resource-name>prod</filter-resource-name>
      </properties>
   </profile>
</profiles>

这一段相信大家都很熟悉了吧,我就不多做解释了(有疑问的童鞋可以私信我哦);

2.然后打开application.properties文件,并在其中加入以下内容:

#表示激活的配置文件(dev|prodspring.profiles.active=@filter-resource-name@

整个项目变成了如下结构:


至此我们的springboot多环境配置已经完成;

3.设置日志级别

#log level
logging.level.root=debug

4.设置自定义端口以及实例名

#端口
server.port=8888

#实例名
spring.application.name=demo-springboot

5.logback-spring.xml

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
   <include resource="org/springframework/boot/logging/logback/base.xml" />

   <appender name="demo" class="ch.qos.logback.core.rolling.RollingFileAppender">
      <file>demo/demo.log</file>
      <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
         <!-- 按天回滚 daily -->
         <fileNamePattern>demo/demo.%d{yyyy-MM-dd}.log</fileNamePattern>
         <!-- 日志最大的历史 10-->
         <maxHistory>10</maxHistory>
      </rollingPolicy>
      <encoder charset="UTF-8">
         <pattern>${FILE_LOG_PATTERN}</pattern>
      </encoder>
   </appender>

   <logger name="com.example.demo" level="INFO" additivity="false">
      <appender-ref ref="demo"/>
   </logger>

   <logger name="com.example.demo.dao" level="DEBUG" />
   <logger name="com.example.demo.service" level="INFO" />

   <logger name="druid.sql.Statement" level="DEBUG" />
   <logger name="druid.sql.ResultSet" level="DEBUG" />
   <logger name="org.apache" level="INFO" />
   <logger name="org.mybatis.spring" level="ERROR" />
   <logger name="org.springframework" level="INFO"></logger>
   <logger name="springfox" level="ERROR"></logger>
   <root level="INFO">
      <appender-ref ref="demo" />
   </root>

</configuration

至此,我们项目的基本环境配置已经搭建好,通过maven clean install以下选择dev|test|prod打入你指定的配置,然后run application运行,如果通过localhost:8888可以访问说明你的配置worked了;但是这还远远不够,我们项目开发总得操作数据库吧,哈哈 是的,接下来让我们进入springboot + mysql + mybatis的世界吧!
