【七】Spring Boot之 自定义starter和autoconfigure

简介

• 自动配置(auto-configuration)
  一项简化配置的功能，比如在classpath中发现有spring security的jar包，则自动创建相关的bean等

• starters(简化依赖)
  这个比较关键，方便spring去集成各类组件，比如redis、mongodb等等。

  • core(security、aop)

  • web(web、websocket、ws、vaadin、rest、mobile)

  • template(freemarker、velocity、groovy templates、thymeleaf)

  • data(jdbc、jpa、mongodb、redis、gemfire、solr、elasticsearch)

  • database(h2、hsqldb、mysql、postgresql)

  • social(facebook、linkedin、twitter)

  • io(batch、integration、jms、amqp)

  • ops(actuator、remote shell)

一、spring-data-redis本来的自动配置怎么用：

我们只需要引入spring-boot-starter-data-redis包就可以使用redis了，不用关心其他依赖的包

这个包中会把我们需要的其他包一起引入

看spring-data-redis中源码的自定义配置

可以知道，它给redis自动配置了一些默认属性，如：

maxActive = 8
maxIdle = 8
minIdle = 0
maxWait = -1

然后我们在引入了autoconfigure和spring-boot-starter-data-redis后，这些默认配置会自动到redis的连接池配置中。如果需要修改指定值，则在application.yml中配置

spring:
  redis:
    database: 0
    host: 192.168.2.240
    password: 123123
    port: 6379
    pool:
      maxActive: 60
      maxIdle: 60
      maxWait: 3000

application.yml没有配置，则Redis的配置用源码中自动配置的属性，如果application.yml有配置，则会被application.yml中的配置覆盖。比如:没有application.yml，则maxToal=8，有application.yml，则maxActive=60

 

二、自定义starter和autoconfigure

使用场景：

工作中有接到如下需求：

1.封装apache http client ，让业务开发的组可以开箱即用，不用关心配置。（这个不介绍，类似的）

2.封装redis，让业务开发组开箱即用，不用关心连接池的配置。这里就有个问题了，spring-data-redis已经做了自动配置了，为什么还要再封装，因为spring-data-redis做的自动配置的那些属性，跟我们期待的标准配置太不一样了。

比如，我们期待的默认配置是

        private int maxIdle = 60;

        private int minIdle = 0;

        private int maxActive = 60;

        private int maxWait = 3000;

        private boolean testOnCreate = false;

        private boolean testOnBorrow = false;

        private boolean testOnReturn = false;

        private boolean testWhileIdle = true;

        private long minEvictableIdleTimeMillis = 70000;

        private long timeBetweenEvictionRunsMillis = 40000;

        private int numTestsPerEvictionRun = -1;

各个业务系统根据实际情况，自己还可以再改。

创建一个项目common-redis-spring-boot

在这个项目中创建两个modules

common-redis-spring-boot-autoconfigure

common-redis-spring-boot-starter

结构如下

1.common-redis-spring-boot

这个工程中不要引入扫描相关的注解，如@Autowire, @componet, @Service, @Controller等

这个工程主要定义子模块的需要用到的jar。

spring-boot-configuration-processor 的作用是编译时生成spring-configuration-metadata.json，在intellij idea中，当配置此jar相关配置属性在application.properties，你可以用ctlr+鼠标左键，IDE会跳转到你配置此属性的类中

}

5.测试

新建一个项目，引入common-redis-spring-boot-starter包

然后直接使用common-redis中的RedisUtil

 ModelTest modelTest = new ModelTest();
 modelTest.setName("小李");
 modelTest.setAge(27);

 RedisUtil.set("common-redis:test:modelTest1",modelTest);
 RedisUtil.set("common-redis:test:string1","测试");

 RedisUtil.get("common-redis:test:string1");
