使用Environment直接读取application.properties参数

package com.tszr.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.core.env.Environment;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class EnvReaderConfigController {
    @Autowired
    private Environment env;

    @RequestMapping("/testEnv")
    public String testEnv(){
        return env.getProperty("test.msg");
    }
}
