这篇文章主要介绍了如何使用SpringBoot自定义starter,具有一定借鉴价值,感兴趣的朋友可以参考下,希望大家阅读完这篇文章之后大有收获,下面让小编带着大家一起了解一下。
springboot一种全新的编程规范,其设计目的是用来简化新Spring应用的初始搭建以及开发过程,SpringBoot也是一个服务于框架的框架,服务范围是简化配置文件。
工程由xxx-sprig-boot-starter
和xxx-sprig-boot-starter-configure
两个模块组成;
xxx-sprig-boot-starter
模块
只用来做依赖导入
依赖于 xxx-sprig-boot-starter-configure
模块,没有实际代码

/**

public class HelloService {
private HelloServiceProperties helloServiceProperties;
public String helloService(String name) {
return helloServiceProperties.getPrefix() + " "+ name + " " + helloServiceProperties.getSuffix();
}
public HelloServiceProperties getHelloServiceProperties() {
return helloServiceProperties;
}
public void setHelloServiceProperties(HelloServiceProperties helloServiceProperties) {
this.helloServiceProperties = helloServiceProperties;
}
}
/**

* @Author: Ander

*/
@ConfigurationProperties(prefix = "com.ander")
public class HelloServiceProperties {
private String prefix = "hi";
private String suffix = "hello world";
public String getPrefix() {
return prefix;
}
public void setPrefix(String prefix) {
this.prefix = prefix;
}
public String getSuffix() {
return suffix;
}
public void setSuffix(String suffix) {
this.suffix = suffix;
}
}
@EnableConfigurationProperties({HelloServiceProperties.class})
作用:让xxxProperties生效加入到容器中
/**
* 自定义starter自动配置类
*
* @Date: 2021-05-04
*/
@Configuration
@ConditionalOnWebApplication // 指定web应用才生效
@EnableConfigurationProperties({HelloServiceProperties.class})
public class HelloServiceAutoConfigure {
@Autowired
private HelloServiceProperties helloServiceProperties;
@Bean
public HelloService helloService() {
HelloService helloService = new HelloService();
helloService.setHelloServiceProperties(helloServiceProperties);
return helloService;
}
}
注意先安装xxx-spring-boot-starter-configure
,再安装xxx-spring-boot-starter
