3 使用方式

引入依赖

代码语言：txt复制

 <!-- https://mvnrepository.com/artifact/com.ctrip.framework.apollo/apollo-client -->
        <dependency>
            <groupId>com.ctrip.framework.apollo</groupId>
            <artifactId>apollo-client</artifactId>
            <version>${apollo-version}</version>
        </dependency>

代码语言：txt复制

spring.application.name=apollo-simple
server.port=7180
app.id=1
apollo.cache-dir=/tmp/data
apollo.meta=http://localhost:8080
apollo.bootstrap.enabled=true
apollo.bootstrap.namespaces=application
apollo.bootstrap.eagerLoad.enabled=true

    }

    @GetMapping("/user/{uid}")
    public IdData info(@PathVariable long uid) {
        IdData idData = new IdData();
        idData.setUid(uid);
        idData.setId("");
        getIdDataFromConfig().ifPresent(

        );
        log.info("apollo-config:"  JacksonTool.toJSONString(config.getPropertyNames()));

        return idData;
    }

    @ApolloConfigChangeListener
    private void changer(ConfigChangeEvent changeEvent) {
        if(changeEvent.isChanged("user_info")) {
            log.info("user_info changeed");
        }
    }
