SpringBoot编写自定义Starter

根据SpringBoot的Starter编写规则,需要编写xxxStarter依赖xxxAutoConfigurer,xxxStarter是一个空的jar,仅提供辅助性的依赖管理,引入其他类库

1.建立一个empty工程,建立一个普通maven模块xxxStarter,建立一个SpringBoot模块xxxAutoConfigurer,前者依赖后者

2.xxxAutoConfigurer:

新建:HelloService:

public class HelloService {

    private HelloProperties helloProperties;

    public void setHelloProperties(HelloProperties helloProperties) {
        this.helloProperties = helloProperties;
    }
    public HelloProperties getHelloProperties() {
        return helloProperties;
    }

    public String hello(){
        return StringFormatter.format("%s:你好,%s欢迎光临",helloProperties.getWeekend(),helloProperties.getName()).getValue();
    }
}

新疆:HelloProperties类

@ConfigurationProperties(prefix = "brx")
public class HelloProperties {

    private String weekend;

    private String name;

    public String getWeekend() {
        return weekend;
    }

    public void setWeekend(String weekend) {
        this.weekend = weekend;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }
}

新建:将启动类修改为一个配置类,并去除pom.xml中的maven插件

@Configuration
@EnableConfigurationProperties(HelloProperties.class)//只有在web上下文才起作用
@ConditionalOnWebApplication
public class BrxautoconfigApplication {

    @Autowired
    HelloProperties helloProperties;

    @Bean
    HelloService helloService(){
        HelloService helloService =  new HelloService();
        helloService.setHelloProperties(helloProperties);
        return helloService;
    }
}

新建:META-INF/spring.factories:

org.springframework.boot.autoconfigure.EnableAutoConfiguration=\
com.brx.demo.brxautoconfig.BrxautoconfigApplication

3.将starter和Autocofigure项目install到本地仓库

4.新建一个普通web项目,并添加xxxStarter库,并在application.properties添加:

brx.weekend="周一"
brx.name="白gg"
