- 后台处理数据库数据(读取数据)
@RequestMapping("/getmanagers")@ResponseBodypublic Map getWorkOrders(String page,String limit,String start,String all){ int pageInt = Integer.parseInt(page); int limitInt = Integer.parseInt(limit); int startInt = Integer.parseInt(start); Map map = new HashMap(); List list = workOrdersService.getWorkOrders(); List listTemp ; //数据库中的结果条数小于分页限制,则直接返回结果 map.put("total",list.size()); if(list.size()=list.size()){ listTemp = list.subList(startInt, list.size()); }else{ listTemp = list.subList(startInt, pageInt*limitInt); } map.put("workOrders", listTemp); return map;}
- ExtMVC
中的model
Ext.define('tw.model.GlobalStatisticsModel',{
extend : 'Ext.data.Model',
fields: [
{name: 'id', type: 'int',sortType :'aesc'},
{name: 'failuretime',type: 'date'},
{name: 'failureaddress', type: 'string'},
{name: 'repairtime', type: 'string'},
{name: 'maintenanceman', type: 'string'},
{name: 'completion', type: 'string'},
{name: 'failurecontent', type: 'string'}
]
});
中的store
Ext.define('tw.store.GlobalStatisticsStore',{
extend:'Ext.data.Store',
model:'tw.model.GlobalStatisticsModel',
pageSize: 17,
proxy:{
type:'ajax',
url: 'gdgl/getmanagers',
reader: {
type: 'json',
root: 'workOrders'
},
writer:{
type: 'json'
}
},
autoLoad: true
});
然后是Ext的View
Ext.define('tw.view.gdgl.GlobalStatisticsView',{
extend : 'Ext.grid.Panel',
xtype : 'globalStatisticsView',
store:'GlobalStatisticsStore',
selType : 'checkboxmodel',
forceFit:false,
columns: [{
text: 'ID',
dataIndex: 'id',
width:50,
editor: {
readOnly:true
}
}, {
// text: '故障时间',
header:'故障时间',
dataIndex: 'failuretime',
width:180,
renderer : Ext.util.Format.dateRenderer('Y-m-d H:i:s'),
editor: {
allowBlank: false
}
}, {
text: '故障地点',
dataIndex: 'failureaddress',
width:200,
editor: {
allowBlank: false
}

Stored procedures are precompiled SQL statements in MySQL for improving performance and simplifying complex operations. 1. Improve performance: After the first compilation, subsequent calls do not need to be recompiled. 2. Improve security: Restrict data table access through permission control. 3. Simplify complex operations: combine multiple SQL statements to simplify application layer logic.

The working principle of MySQL query cache is to store the results of SELECT query, and when the same query is executed again, the cached results are directly returned. 1) Query cache improves database reading performance and finds cached results through hash values. 2) Simple configuration, set query_cache_type and query_cache_size in MySQL configuration file. 3) Use the SQL_NO_CACHE keyword to disable the cache of specific queries. 4) In high-frequency update environments, query cache may cause performance bottlenecks and needs to be optimized for use through monitoring and adjustment of parameters.

The reasons why MySQL is widely used in various projects include: 1. High performance and scalability, supporting multiple storage engines; 2. Easy to use and maintain, simple configuration and rich tools; 3. Rich ecosystem, attracting a large number of community and third-party tool support; 4. Cross-platform support, suitable for multiple operating systems.

The steps for upgrading MySQL database include: 1. Backup the database, 2. Stop the current MySQL service, 3. Install the new version of MySQL, 4. Start the new version of MySQL service, 5. Recover the database. Compatibility issues are required during the upgrade process, and advanced tools such as PerconaToolkit can be used for testing and optimization.
