读取数据并显示：

package org.example.controller;
    
    import org.springframework.beans.factory.annotation.Value;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RestController;
    
    
    @RestController
    public class ValueReaderConfigController
    {
    
        @Value("${test.environment}")
        private String msg;
    
        //  http://localhost:8080/testValue
    
        @RequestMapping("/testValue")
        public String testValue()
        {
    
            return "方法二：" + msg;
        }
    }
