关于拼接SQL语句sqlMap的使用方法

/**
* 自定义SQL（SQL标识，SQL内容）

protected Map<String, String> sqlMap;
@JsonIgnore
@XmlTransient
public Map<String, String> getSqlMap() {
if (sqlMap == null){
sqlMap = Maps.newHashMap();
}
return sqlMap;
}
public void setSqlMap(Map<String, String> sqlMap) {
this.sqlMap = sqlMap;
}

</select>

public Page<ZlfbBean> findzlfb(Page<ZlfbBean> page,ZlfbBean bean){
// 生成数据权限过滤条件（dsf为dataScopeFilter的简写，在xml中使用 ${sqlMap.dsf}调用权限SQL）
User user = UserUtils.getUser();
String dsf = dataScopeFilter( user, "l", "k");//返回的是如AND (k.id='user.getId()')
if((bean.getCreateBy()==null || bean.getCreateBy().getId().equals("")) && (bean.getOffice()==null || bean.getOffice().getId().equals(""))){
dsf = dsf+" OR i.zlbh IN( "
+" SELECT  DISTINCT t1.zlbh FROM ZL_HCZZ t1 join ZL_HCZZSP t2 on t1.zlbh=t2.zlbh where t2.CREATE_BY = "+user.getId()
+" ) "
+" OR i.zlbh IN( "
+" SELECT  DISTINCT t1.zlbh FROM ZL_HCZZ t1 join ZL_HCZZQS t2 on t1.zlbh=t2.zlbh where t2.CREATE_BY = "+user.getId()+" OR ((SELECT COUNT(1) FROM SYS_USER WHERE id="+user.getId()+" and qsqx='01' and office_id='"+user.getOffice().getId()+"') > 0 ) AND t2.QS_DW = '"+user.getOffice().getId()+"' "
+" ) "
+" OR i.zlbh IN( "
+" SELECT  DISTINCT t1.zlbh FROM ZL_HCZZ t1 join ZL_HCZZFK t2 on t1.zlbh=t2.zlbh where t2.CREATE_BY = "+user.getId()
+" ) ";
}
bean.getSqlMap().put("dsf", dsf);给sqlmap集合中添加值，即添加一个dsf字符串的值为dsf
// 设置分页参数
bean.setPage(page);
// 执行分页查询
page.setList(zlfbDao.findList(bean));
return page;
