java web项目 demo_java web项目简单查询demo前后台完整代码
1、前台页面jsp
2、前台js
//添加搜索框
addSearchBox:function(width){
$('.searchbox').css({'width': width+'px'});
$('.searchbox-text').css({'width': eval(width-20)+'px'});
$('.datagrid-toolbar').append($('.serarchbox'));
$('.datagrid-toolbar').append($('#tbar'));
},
//查询
doSearch:function(value){
if($.trim(value) ==""){
Ict.info("请输入查询条件!");
return;
}
$('#systemUserGrid').datagrid({
url : '/pc/systemUser/queryUserList.htm',
queryParams : {
'keyWord' : value,
},
toolbar : '#toolBar'
});
},
3、后台controller
/**
* 查询系统用户列表.
* @param page
* @param rows
* @param idIcon
* @param keyWord
* @return Map
*/
@RequestMapping("queryUserList.htm")
@ResponseBody
public Map queryUserList(int page, int rows, String idIcon,String keyWord){
User user = SecurityContextUtil.getCurrentUser();
String companyId = SecurityContextUtil.getCompanyId();
String roleCode = user.getRoles().get(0).getRoleCode();
String[] typeAndId = new String[]{};
String departmentIds = "";
String employeeId = "";
if("0".equals(roleCode)){
if(StringUtils.hasText(idIcon)){
typeAndId = idIcon.split("_");
if("company".equals(typeAndId[1])){
companyId = typeAndId[0];
}else{
Department department = this.departmentService.getEntity(typeAndId[0]);
departmentIds = this.departmentService.allChildrenDept(department.getDepartmentId());
}
}else{
companyId = "";
departmentIds = "";
}
}else if("4".equals(roleCode)){
if(StringUtils.hasText(idIcon)){
typeAndId = idIcon.split("_");
if("company".equals(typeAndId[1])){
companyId = typeAndId[0];
}else{
departmentIds = this.departmentService.allChildrenDept(typeAndId[0]);
}
}else{
departmentIds = "";
}
}else if("3".equals(roleCode)){
Employee employee = this.sysEmployeeService.getEmployee(user.getEmployeeId());
if(StringUtils.hasText(idIcon)){
typeAndId = idIcon.split("_");
if("company".equals(typeAndId[1])){
companyId = typeAndId[0];
departmentIds = this.departmentService.allChildrenDept(employee.getDepartmentId());
}else{
departmentIds = this.departmentService.allChildrenDept(typeAndId[0]);
}
}else{
departmentIds = this.departmentService.allChildrenDept(employee.getDepartmentId());
}
}else{
employeeId = user.getEmployeeId();
}
return this.systemUserPCService.queryUserList(page, rows, keyWord, departmentIds, companyId, employeeId);
}
4.后台service层
public Map queryUserList(int page, int rows, String keyWord,String departmentIds, String companyId, String employeeId) {
return this.systemUserPCDao.queryUserList(page, rows , keyWord, departmentIds, companyId, employeeId);
}
5、后台dao层
public Map queryUserList(int page, int rows, String keyWord,String departmentIds, String companyId, String employeeId) { int offset = (page - 1)* rows; String rowSql = "SELECT ur.id as id , " + "com.company_name AS companyName , " + " ro.role_name AS roleName , " + " emp.employee_code AS employeeCode , " + " emp.employee_name AS realName , " + " su.user_name AS userName, " + " emp.mobile AS mobile ," + " su.login_time AS loginTime " + " FROM tb_c_user_role ur ,tb_c_role ro , tb_c_system_user su , " + " tb_c_company com ,tb_c_employee emp " + " WHERE com.company_id = su.company_id " + " AND su.user_id = ur.user_id AND ro.role_id = ur.role_id " + "AND emp.employee_id = su.employee_id " + " AND su.del_flag = '0' "; String countSql = "select count(ur.id) " + " FROM tb_c_user_role ur ,tb_c_role ro , tb_c_system_user su , " + " tb_c_company com ,tb_c_employee emp " + " WHERE com.company_id = su.company_id " + " AND su.user_id = ur.user_id AND ro.role_id = ur.role_id " + " AND emp.employee_id = su.employee_id " + " AND su.del_flag = '0' "; if(StringUtils.hasText(departmentIds)){ rowSql += " AND emp.employee_id IN ( SELECT a.employee_id FROM tb_c_employee a , " + " tb_c_department b WHERE a.department_id = b.department_id AND b.department_id IN( " + departmentIds + " ))"; countSql += " AND emp.employee_id IN ( SELECT a.employee_id FROM tb_c_employee a , " + " tb_c_department b WHERE a.department_id = b.department_id AND b.department_id IN( " + departmentIds + " ))"; } if(StringUtils.hasText(companyId)){ rowSql += " and com.company_id = '" + companyId + "' "; countSql += " and com.company_id = '" + companyId + "' "; } if(StringUtils.hasText(employeeId)){ rowSql += " and emp.employee_id = '" + employeeId + "' "; countSql += " and emp.employee_id = '" + employeeId + "' "; } if(StringUtils.hasText(keyWord)){ rowSql += "and ( emp.employee_name like '%" + keyWord.trim() + "%' or emp.mobile like '%" + keyWord.trim() + "%' )"; countSql += "and ( emp.employee_name like '%" + keyWord.trim() + "%' or emp.mobile like '%" + keyWord.trim() + "%' )"; } rowSql += " limit ?,?"; List> list = this.jdbcTemplate.queryForList (rowSql, offset, rows); int total = this.jdbcTemplate.queryForInt(countSql); Map map = new HashMap<>(); map.put("rows", list); map.put("total", total); return map; }
