按照上一篇的内容，有一些缺陷的地方。
分页对象传什么都可以，但是返回的是list<HashMap<String,Object>>集合的话，分页方法就是无效了。

这里把我写的贴一下:

Controller:

// 带条件分页Integer pageNo = null;Integer pageSize = null;if (request.getParameter("pageNo") != null) {pageNo = Integer.parseInt((String) request.getParameter("pageNo"));} else {page.setPageNo(1);pageNo = 1;}if (request.getParameter("pageSize") != null) {pageSize = Integer.parseInt((String) request.getParameter("pageSize"));} else {pageSize = 30;}page.setPageNo(pageNo);page.setPageSize(pageSize);//根据条件查到的集合List<Map<String, Object>> list = busMddkApplicationService.findPage(page, params);page.setList(list);model.addAttribute("page", page);

获取前台传过来的页码和分页数，这样再set到page对象中，前台就可以显示正常的分页和页码了。

jsp页面：

<form:form id="searchForm" modelAttribute="baseBusMddkApplication" action="${ctx}/contract/busMddkApplication/" method="post" class="breadcrumb form-search"><input id="pageNo" name="pageNo" type="hidden" value="${page.pageNo}"/><input id="pageSize" name="pageSize" type="hidden" value="${page.pageSize}"/>
</form:form>

jsp页面，没改过，就用他生成的就可以。


再说一下shiro的自定义标签：

<shiro:hasAnyPermissions name="contract:busMddkApplication:edit,contract:busMddkApplication:add"></shiro:hasAnyPermissions>

<shiro:hasAnyPermissions ></shiro:hasAnyPermissions>这个标签的意思是有任一权限就可以

<shiro:hasPermission name="contract:busMddkApplication:edit">

<shiro:hasAnyPermissions ></shiro:hasAnyPermissions>这个标签的意思是有某个权限

Controller:

@RequiresPermissions(value= {"contract:busMddkApplication:active","contract:busMddkApplication:edit","contract:busMddkApplication:add","contract:busMddkApplication:info"})
@RequestMapping(value = "form")protected String form(HttpServletRequest request, BusMddkApplicationVo busMddkApplicationVo2, Model model,HttpServletResponse response, RedirectAttributes redirectAttributes) { }

上面的意思是有任一权限就可以进入这个方法。
这是说一下分页的问题,可以用他的page对象，会进入pageInterceptor的拦截器。感觉他查询总数的方法有点问题。贴一下原来的和我改动的代码。


//得到总记录数

common.persistence.interceptor.SQLHelper包下面，在PaginationInterceptor里边先调用 

page.setCount(SQLHelper.getCount(originalSql, null, mappedStatement, parameterObject, boundSql, log));

贴一下他原来的getCount()方法。

public static int getCount(final String sql, final Connection connection,final MappedStatement mappedStatement, final Object parameterObject,final BoundSql boundSql, Log log) throws SQLException {String dbName = Global.getConfig("jdbc.type");final String countSql;if("oracle".equals(dbName)){countSql = "select count(1) from (" + sql + ") tmp_count";//需要优化的sql}else{countSql = "select count(1) from (" + removeOrders(sql) + ") tmp_count";}Connection conn = connection;PreparedStatement ps = null;ResultSet rs = null;try {if (log.isDebugEnabled()) {log.debug("COUNT SQL: " + StringUtils.replaceEach(countSql, new String[]{"\n","\t"}, new String[]{" "," "}));}if (conn == null){conn = mappedStatement.getConfiguration().getEnvironment().getDataSource().getConnection();}ps = conn.prepareStatement(countSql);BoundSql countBS = new BoundSql(mappedStatement.getConfiguration(), countSql,boundSql.getParameterMappings(), parameterObject);//解决MyBatis 分页foreach 参数失效 startif (Reflections.getFieldValue(boundSql, "metaParameters") != null) {MetaObject mo = (MetaObject) Reflections.getFieldValue(boundSql, "metaParameters");Reflections.setFieldValue(countBS, "metaParameters", mo);}//解决MyBatis 分页foreach 参数失效 end SQLHelper.setParameters(ps, mappedStatement, countBS, parameterObject);rs = ps.executeQuery();int count = 0;if (rs.next()) {count = rs.getInt(1);}return count;} finally {if (rs != null) {rs.close();}if (ps != null) {ps.close();}if (conn != null) {conn.close();}}}/** * 去除hql的orderBy子句。 * @param hql * @return */  @SuppressWarnings("unused")private static String removeOrders(String qlString) {  Pattern p = Pattern.compile("order\\s*by[\\w|\\W|\\s|\\S]*", Pattern.CASE_INSENSITIVE);  Matcher m = p.matcher(qlString);  StringBuffer sb = new StringBuffer();  while (m.find()) {  m.appendReplacement(sb, "");  }m.appendTail(sb);return sb.toString();  }

 这样生成的sql就是正常的条件查询语句外面包了一层select count(1) from(原sql)。
    但是在实际使用过程中，数据量比较大(百万级别),并且查询条件和参数很多的时候,这样会很慢。不如直接select count(1) from (***) 这样的快。
    所以改写了他的getCount()方法,在需要优化的sql的where后边加上'needOptimization' = 'needOptimization'。

public static int getCount(final String sql, final Connection connection,final MappedStatement mappedStatement, final Object parameterObject,final BoundSql boundSql, Log log) throws SQLException {String dbName = Global.getConfig("jdbc.type");final String countSql;if("oracle".equals(dbName)){countSql = "select count(1) from (" + sql + ") tmp_count";//需要优化的sql}else if(sql.contains("needOptimization")){countSql = "select count(1) from "+ removeContent(sql);}else{countSql = "select count(1) from (" + removeOrders(sql) + ") tmp_count";}Connection conn = connection;PreparedStatement ps = null;ResultSet rs = null;try {if (log.isDebugEnabled()) {log.debug("COUNT SQL: " + StringUtils.replaceEach(countSql, new String[]{"\n","\t"}, new String[]{" "," "}));}if (conn == null){conn = mappedStatement.getConfiguration().getEnvironment().getDataSource().getConnection();}ps = conn.prepareStatement(countSql);BoundSql countBS = new BoundSql(mappedStatement.getConfiguration(), countSql,boundSql.getParameterMappings(), parameterObject);//解决MyBatis 分页foreach 参数失效 startif (Reflections.getFieldValue(boundSql, "metaParameters") != null) {MetaObject mo = (MetaObject) Reflections.getFieldValue(boundSql, "metaParameters");Reflections.setFieldValue(countBS, "metaParameters", mo);}//解决MyBatis 分页foreach 参数失效 end SQLHelper.setParameters(ps, mappedStatement, countBS, parameterObject);rs = ps.executeQuery();int count = 0;if (rs.next()) {count = rs.getInt(1);}return count;} finally {if (rs != null) {rs.close();}if (ps != null) {ps.close();}if (conn != null) {conn.close();}}}/*** 将第一个from前的内容删除* @Description:TODO* @author:gmwang* @time:2017年8月29日 上午10:16:28*/private static String removeContent(String sql) {String sqlAfter = StringUtils.substringAfter(sql,"FROM");return sqlAfter;}

如果原来是select count(1) from (
select a.*,b.* from aa a 
left join bb b on a.id = b.id
)
现在就改成了 select count(1) from aa a left join bb b on a.id = b.id
原来的sql执行24秒,现在大约是6秒。
