有关于邮箱发送的java代码

String user = "1xxxxxxxx";

String code = "jasdifoherusdf";

String host = "smtp.qq.com";

boolean auth = true;

信息书写

application.yml

email:
    user: 1xxxxxxxx
    code: jasdifoherusdf
    host: smtp.qq.com
    auth: true

获取yml的值

@Value(“${键名}”)

@Value("${email.user}")
private String user;

@RequestMapping("/hello")
public String hello() {
    return user;
}

如果觉得每次获取都需要前缀.属性比较麻烦，可以使用@ConfigurationProperties(prefix = "前缀")，就不需要@Value()了

• 要有实体类(实体类的成员属性要跟yml配置的键名一致)

package com.walker.pojo;

import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;

@Component
@ConfigurationProperties(prefix = "email")
public class Email {
    private String user;
    private String code;
    private String host;
    private boolean auth;
}

• 使用

package com.walker.controller;

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

@RestController
public class HelloController {

    private String user;

    @RequestMapping("/hello")
    public String hello() {
        return user;
    }
}
