@Configuration:这个配置就不用多做解释了,我们一直在使用
@EnableConfigurationProperties:这是一个开启使用配置参数的注解,value值就是我们配置实体参数映射的ClassType,将配置实体作为配置来源。
SpringBoot内置条件注解
有关@ConditionalOnXxx相关的注解这里要系统的说下,因为这个是我们配置的关键,根据名称我们可以理解为具有Xxx条件,当然它实际的意义也是如此,条件注解是一个系列,下面我们详细做出解释
@ConditionalOnBean:当SpringIoc容器内存在指定Bean的条件
@ConditionalOnClass:当SpringIoc容器内存在指定Class的条件
@ConditionalOnExpression:基于SpEL表达式作为判断条件
@ConditionalOnJava:基于JVM版本作为判断条件
@ConditionalOnJndi:在JNDI存在时查找指定的位置
@ConditionalOnMissingBean:当SpringIoc容器内不存在指定Bean的条件
@ConditionalOnMissingClass:当SpringIoc容器内不存在指定Class的条件
@ConditionalOnNotWebApplication:当前项目不是Web项目的条件
@ConditionalOnProperty:指定的属性是否有指定的值
@ConditionalOnResource:类路径是否有指定的值
@ConditionalOnSingleCandidate:当指定Bean在SpringIoc容器内只有一个,或者虽然有多个但是指定首选的Bean
@ConditionalOnWebApplication:当前项目是Web项目的条件
以上注解都是元注解@Conditional演变而来的,根据不用的条件对应创建以上的具体条件注解。

至此结束配置类,然后把这个项目打包程jar。
接着新建starter maven 工程:
pom.xml:
<?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"

<java.version>1.8</java.version>
</properties> <dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter</artifactId>
</dependency>
<!-- 依赖刚刚自定义的配置jar-->
<dependency>
<groupId>com.hnnd</groupId>
<artifactId>redisoper-spring-boot-autoconfiguration</artifactId>
<version>0.0.1-SNAPSHOT</version>
</dependency>
</dependencies> </project>
application.properties:
spring.redis.redis-server-ip=localhost
spring.redis.redis-server-port=6379
spring.redis.redis-pass=
至此starter 工程 就可以直接使用在autoConfiguration工程自己配置的RedisOperClient 类 来操作redis,如果您把starter工程jar 包放在公司私服,那么同事就都能用你配置好的组件。多爽? 你就是传说的架构师。
