使用@Value给属性参数赋值

package com.tszr.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("天生自然")
    private String msg;

    @RequestMapping("/testValue")
    public String testValue() {
        return msg;
    }
}
