系统日志管理
-
（1）分析
记录用户的访问的Controller与ip等信息
属于监控功能
只要查看与保存功能 -
（2）数据组成
//设置登录用户信息seesion获取
//设置企业信息
//IP地址request获取
//设置记录时间
//执行的方法名称新方法获取
//执行的类名称
系统日志管理
两个功能，一个是分页显示，一个是保存日志
》SysLog
》TestSysLogService
》ISysLogService,SysLogServiceImpl
》 ISysLogDao,ISysLogDao.xml
》SysLogController,xxx.jsp
SysLog
public class SysLog {
private String id ;
private String userName ;
private String ip ;
private Date time ;
private String method ;
private String action ;
private String companyId ;
private String companyName ;
TestSysLogService
分页查询
添加
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("classpath*:spring/applicationContext-*.xml")
public class TestSysLogService {
@Autowired
ISysLogService iSysLogService;
//增*删改查*
@Test
public void test01(){
//分页列表
//页面上显示分页列表，就要求业务方法中提供查询PageInfo的方法
PageInfo<SysLog> pi= iSysLogService.findByPage(1,3,"1");
}
@Test
public void test02(){
//将一个表单数据保存在javaBean中，再将javaBean存到数据库
SysLog sysLog = new SysLog();
//设置登录用户信息
sysLog.setUserName("老玉");
//设置企业信息
sysLog.setCompanyId("1");
sysLog.setCompanyName("吉首大学");
//IP地址
sysLog.setIp("192.168.10.11");
//设置记录时间
sysLog.setTime(new Date());
//执行的方法名称
sysLog.setMethod("toList");
//执行的类名称
sysLog.setAction("com.wzx.web.company.CompanyController");
sysLog.setCompanyId("1");
sysLog.setCompanyName("吉首大学");
iSysLogService.saveSysLog(sysLog);
}
}

系统日志管理 优化日志列表
- （1）分析
日志记录多，生成的页号按钮多 - （2）实现
控制循环次数
并进行边界判断
base.jsp
<c:forEach begin="${pi.pageNum-5 <= 0 ? 1:pi.pageNum-5 }" end="${pi.pageNum+5>pi.pages?pi.pages:pi.pageNum+5}"
var="i">
<li class="paginate_button ${pi.pageNum==i ? 'active':''}"><a href="javascript:goPage(${i})">${i}</a></li>
</c:forEach>
