Mybatis注解开发传入集合参数

今天又一个需求，是查询是传入的是一个集合的参数，而使用的是注解的开发，并且条件是有多个，根据是否为空，进行动态的变动处理，所以不能使用<script></script>的方式，只能使用单独的类进行封装sql,实现的代码如下：

Mybatis方法：

Mybatis调用方法：

 @SelectProvider(type = RoleMapper.RoleDaoProvider.class, method = "findAll")
 List<AdministratorRole> findAll(AdministratorRole role,List<Long> parentIdList);

内部类：

 class UserDaoProvider {
       public String findAll(AdministratorRole role,List<Long> parentIdList) {
            SQL sql = new SQL() {
                {
                    SELECT( "t1.*,t2.agent_name" );
                    FROM( "administrator_role t1 " );
                    LEFT_OUTER_JOIN( " agent t2 on t1.agent_id = t2.agent_id" );
                    WHERE( "t1.is_delete=0" );
                    if (StringUtils.isNotBlank( role.getRole_name() )) {
                        WHERE( " t1.role_name like \"%"+role.getRole_name()+"%\" " );
                    }

                }
            };
            String sqlStr = sql.toString();
            //代理商查询条件
            if (parentIdList!= null && parentIdList.size()>0) {
                sqlStr +=" and t1.agent_id  in (";
                for ( int i=0;i<parentIdList.size();i++) {
                    if(i == parentIdList.size()-1){
                        sqlStr += parentIdList.get( i );
                        break;
                    }
                    sqlStr += parentIdList.get( i )+",";
                }
                sqlStr +=" )";
            }

            if(StringUtils.isNotEmpty( role.getOpenFlag() )){
                if("1".equals( role.getOpenFlag())){
                    sqlStr+= " order by t1.is_disable desc" ;
                }
                if("0".equals( role.getOpenFlag())){
                    sqlStr+= " order by t1.is_disable asc";
                }
            }
            if(StringUtils.isNotEmpty( role.getOrderTime() )){
                if(StringUtils.isNotEmpty( role.getOpenFlag() )){
                    if("1".equals( role.getOrderTime() )){
                        sqlStr+= " , t1.create_datetime desc";
                    }
                    if("0".equals( role.getOrderTime() )){
                        sqlStr+= " , t1.create_datetime asc";
                    }
                }else{
                    if("1".equals( role.getOrderTime() )){
                        sqlStr+= " order by t1.create_datetime desc";
                    }
                    if("0".equals( role.getOrderTime() )){
                        sqlStr+= " order by t1.create_datetime asc";
                    }
                }


            }

            Integer pageNo = role.getPageNo();
            Integer pageSize = role.getPageSize();

            if (pageNo != null && pageSize != null) {
                int first = (pageNo - 1) * pageSize;

                sqlStr += " limit " + first + "," + pageSize;
            }

            return sqlStr;
        }
