Day39项目saas-export项目-系统日志管理**

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 {
    private static final Logger l = LoggerFactory.getLogger(TestSysLogService.class);
    @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");
        l.info("pi = "+pi);
    }
  @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);

    }


}

ISysLogService,SysLogServiceImpl

public interface ISysLogService {
    PageInfo<SysLog> findByPage(int curr, int pageSize, String companyId);
    void saveSysLog(SysLog sysLog);
}

@Service
public class SysLogServiceImpl implements ISysLogService {
    //service调用dao
    @Autowired
    ISysLogDao iSysLogDao;
    @Override
    public PageInfo<SysLog> findByPage(int curr, int pageSize, String companyId) {
        //设置参数
        PageHelper.startPage(curr,pageSize);
        //调用全查
        List<SysLog> list = iSysLogDao.findAll(companyId);
        //包装成PageInfo
        PageInfo<SysLog> pi = new PageInfo<>(list);
        return pi;
    }

    @Override
    public void saveSysLog(SysLog sysLog) {
        String uuid= UUID.randomUUID().toString();
        sysLog.setId(uuid);
        iSysLogDao.save(sysLog);
    }
}

ISysLogDao,ISysLogDao.xml

public interface ISysLogDao {
    List<SysLog> findAll(String companyId);
    void save(SysLog sysLog);
}

                    </c:forEach>

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

<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>
