        .innerJoin(o -> o.eq(UserRoleEntity.class, RoleEntity.class, UserRoleEntity::getRoleId, RoleEntity::getId))
        .where(o -> o.and(UserEntity::getUserName, "11").and(UserRoleEntity.class, UserRoleEntity::getRoleId, "1")).buildSql();
        

使用方法
在实体类上，继承BaseEntity，添加@EnableAutoApi注解即可

示例
@Setter
@Getter
@TableName("t_user")
@EnableAutoApi
public class UserEntity extends BaseEntity {

    private String userName;

    private String password;
}
