简单的SpringBootStarter

新建项目

创建配置类

@ConfigurationProperties("zhangfei.hello")
public class HelloProperties {
    private String name;

    public String getName() {
        return name;
    }

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

创建对外提供的接口

public class MyStartController {
    HelloProperties helloProperties;
    public MyStartController(HelloProperties helloProperties) {
        this.helloProperties=helloProperties;
    }
    public String index(){
        return helloProperties.getName()+"欢迎您";
    }
}

启动类

启动类
首先看引用项目的配置是否有zhangfei.hello.name 这个属性
有的话加载HelloProperties.class 然后开始注入bean信息（MyStartController ）
外部引入jar包即可用

@Configuration
@ConditionalOnProperty(value = "zhangfei.hello.name")
@EnableConfigurationProperties(HelloProperties.class)
public class HelloAutoConfitguration {

    @Autowired
    HelloProperties helloProperties;

    @Bean
    public MyStartController indexController(){
        return new MyStartController(helloProperties);
    }
}

启动类向导

这个一定注意
- resources下创建META-INF
- 在META-INF下创建文件spring.factories 而不是在创建再创建spring文件夹然后再创建
- 如果factories文件
- 如果META-INF下面创建spring的话再spring文件夹创建org.springframework.boot.autoconfigure.AutoConfiguration.imports是可以的

org.springframework.boot.autoconfigure.EnableAutoConfiguration=com.gouying.web.config.HelloAutoConfitguration
