spring boot 使用spring.resources.static-locations 分离系统模版&&资源文件

方便我们将资源配置以及模版&&静态文件分离出来，而不是打包在一起，比如以下的一个demo

参考配置：

server.port=8006
spring.application.name=appdemo
spring.resources.static-locations=pdf
spring.resources.chain.cache=false

maven 配置

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.io.File;
import java.io.IOException;
import java.nio.file.Files;
import java.util.HashMap;
import java.util.Map;
@RestController

public Object productsList() throws IOException {

     Map<String,String> products=new HashMap<>();
     products.put("name","appdemo");
     products.put("amount","10");
     File file = new File("pdf/myinfo.txt");
     products.put("myfile",file.getCanonicalPath());
