MyBatis - @Param 注解对象是否使用区别？

不使用注解@Param?

List<LogBO> listUserTenantLogs(LogQuery logQuery);

<select id="listUserTenantLogs">
    SELECT * FROM t_user
    <where>
        <if test="code != null and code != ''">
            AND code = #{code}
        </if>
    </where>
</select>

使用注解@Param

List<LogBO> listUserTenantLogs(@Param("logQuery") LogQuery logQuery);

<select id="listUserTenantLogs">
    SELECT * FROM t_user
    <where>
        <if test="logQuery.code != null and logQuery.code != ''">
            AND code = #{logQuery.code}
        </if>
    </where>
</select>

总结

• 使用注解时，XML 必须添加对应的注解 value.xxx 才行?
