配置的读取方式在上一篇文章中有提到。
取到值之后赋值给静态类里的静态变量。
因为SpringCloud项目启动的时候会把所有的api都执行一遍(相当蛋疼)，所以这里直接就可以写一个方法进行赋值。

代码如下：

入口类：

package com.shinho;import java.util.Map;import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;import com.alibaba.fastjson.JSON;
import com.shinho.log.ShinhoLog;@Configuration
@EnableAutoConfiguration
@ComponentScan(basePackages={"com.shinho"})
@EnableWebMvc
@EnableEurekaClient
@RestController
public class KylintestApplication { @Value("${foo}")
String foo; private static final Logger logger = LoggerFactory.getLogger(KylintestApplication.class); public static void main(String[] args) {
SpringApplication.run(KylintestApplication.class, args);
} @RequestMapping("/log")
@Bean
public String Log() {
logger.info("init:log");
ShinhoLog.foo = this.foo;
String json = "log";
return json;
} @RequestMapping("/hi")
@Bean
public String home() {
String json = "123:"+ShinhoLog.info();
return json;
}
}

静态类：

package com.shinho.log;import java.io.File;import org.apache.commons.io.FileUtils;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.stereotype.Component;@Component
public class ShinhoLog { public static String foo; public static String info(){
return foo;
}}

启动之后立即访问 http://localhost:XXXX/hi 这是会返回123:foo version 2，完美！
