本文详细介绍了如何配置Spring Boot应用，包括端口、Thymeleaf缓存、数据库连接、MyBatis映射文件、邮件发送及用户实体与加密。重点展示了User类、密码加密工具和注册、激活流程。

配置信息

# ServerProperties
server.port=8080
server.servlet.context-path=/community

# ThymeleafProperties
spring.thymeleaf.cache=false

# DataSourceProperties
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/community?characterEncoding=utf-8&useSSL=false&serverTimezone=Hongkong
spring.datasource.username=root
spring.datasource.password=123456
spring.datasource.type=com.zaxxer.hikari.HikariDataSource
spring.datasource.hikari.maximum-pool-size=15
spring.datasource.hikari.minimum-idle=5
spring.datasource.hikari.idle-timeout=30000

# MybatisProperties
#mapper类和mapper.xml不在同一个路径下时,指定mapper.xml的路径
mybatis.mapper-locations=classpath:mapper/*.xml
#取别名
mybatis.type-aliases-package=com.nowcoder.community.entity
#如果插入的表以自增列为主键，则允许 JDBC 支持自动生成主键，并可将自动生成的主键返回
mybatis.configuration.useGeneratedKeys=true
#自动转换驼峰命名
mybatis.configuration.mapUnderscoreToCamelCase=true


# MailProperties
# 访问邮箱的域名 smtp表示协议
spring.mail.host=smtp.qq.com
spring.mail.username=****@qq.com
#授权码
spring.mail.password=*****
spring.mail.protocol=smtps
# 采用ssl安全连接
spring.mail.properties.mail.smtp.ssl.enable=true


# 自定义KV
community.path.domain=http://localhost:8080

实体类

public class User {
    private int id;
    private String username;
    private String password;
    private String salt;
    private String email;
    private int type;
    private int status;
    private String activationCode;
    private String headerUrl;
    private Date createTime;
    //setget方法
}

密码加密工具类

public class CommunityUtil {

    // 生成随机字符串
    public static String generateUUID() {
        return UUID.randomUUID().toString().replaceAll("-", "");
    }

    // MD5加密
    public static String md5(String key) {
        if (StringUtils.isBlank(key)) {
            return null;
        }
        return DigestUtils.md5DigestAsHex(key.getBytes());
    }

}

Mapper层

dao接口

@Mapper
public interface UserMapper {

    User selectById(int id);

    User selectByName(String username);

    User selectByEmail(String email);

    int insertUser(User user);

    int updateStatus(int id, int status);

    int updateHeader(int id, String headerUrl);

    int updatePassword(int id, String password);

}

mapper.xml

<mapper namespace="com.nowcoder.community.dao.UserMapper">

    <sql id="insertFields">
        username, password, salt, email, type, status, activation_code, header_url, create_time
    </sql>

    <sql id="selectFields">
        id, username, password, salt, email, type, status, activation_code, header_url, create_time
    </sql>

    <select id="selectById" resultType="User">
        select <include refid="selectFields"></include>
        from user
        where id = #{id}
    </select>

    <select id="selectByName" resultType="User">
        select <include refid="selectFields"></include>
        from user
        where username = #{username}
    </select>

    <select id="selectByEmail" resultType="User">
        select <include refid="selectFields"></include>
        from user
        where email = #{email}
    </select>

    <insert id="insertUser" parameterType="User" keyProperty="id">
        insert into user (<include refid="insertFields"></include>)
        values(#{username}, #{password}, #{salt}, #{email}, #{type}, #{status}, #{activationCode}, #{headerUrl}, #{createTime})
    </insert>

    <update id="updateStatus">
        update user set status = #{status} where id = #{id}
    </update>

    <update id="updateHeader">
        update user set header_url = #{headerUrl} where id = #{id}
    </update>

    <update id="updatePassword">
        update user set password = #{password} where id = #{id}
