LigerUI中 ligerListBox 控件怎么分页

Java代码
grid = $("#maingrid").ligerGrid({
height:'80%',
width:"100%",
columns: [
{ display: '项目名称', name: 'projectName', align: 'left', width: 100, minWidth: 60 },
{ display: '街镇名称', name: 'projectStreet', minWidth: 120 }

],
url:"${pageContext.request.contextPath}/houseStore/page",

root:"content",
record:"totalItems",
pagesizeParmName:"pageSize",
pageParmName:" currentPage",
pageSize:20,
method:"post",
dataAction:"server",
rownumbers:true,checkbox: true,
toolbar: { items: [
{ text: '增加', click: addObj, icon: '' },
{ line: true },
{ text: '修改', click: updateObj, icon: '' },
{ line: true },
{ text: '删除', click: deleteObj, icon: '' }
]
}
});
，后台代码如下
Java代码
public ResponseEntity> page(@RequestParam(value="currentPage",required=false) Integer currentPage,@RequestParam(value="pageSize",required=false) Integer pageSize){

}
