SSH程序开发参考文档一、简单查询页面程序开发1阅读相关Use Case，并检查是否有问题。2根据Use Case，查看相关表及其对应的Model文件。3创建相应的资源文件。3.1 根据Use Case上的页面概样及相关信息创建资源文件 src/resource/manager/userManagement/UserMpertiesusercontroltop.menu.lable.title = 用户管理usercontroltop.menu.lable.add = 添加usercontroltop.menu.lable.maintain = 编辑usercontroltop.menu.maintain.maintain = 用户编辑usercontroltop.menu.lable.display = 显示usercontroltop.menu.display.user = 用户显示usercontroltop.menu.lable.delete = 删除 = 用户管理usercontroltop.grid.column.userid = 用户代码user.maintain.label.firstname = 用户名user.maintain.form.userStatus = 用户状态user.control.label.branch = 分公司usercontroltop.grid.column.entity = 默认实体user.control.label.usertype = 用户类型usercontroltop.grid.column.group = 部门user.control.label.loggedon = 登录此工作通过一个专门的Excel自动生成文件生成。3.2 创建Strust的resource配置文件 WebRoot/WEB-INF/conf/struts/ userManagement-resource.xml创建完成后，必须在WebRoot/WEB-INF/conf/struts/struts-config.xml中的相应位置追加此文件（记得一定要在相应位置追加，黄色标记为追加）src/config/struts/struts-config.xml!DOCTYPE struts-config PUBLIC -/Apache Software Foundation/DTD Struts Configuration 1.2/EN /struts/dtds/struts-config_1_2.dtd -省略- -省略-&userManagement-resource; 4创建Form文件4.1根据页面创建Form的java文件com/pw/authority/form /UserManagementForm.javapackage com.pw.authority.form;import mon.beans.BaseActionForm;public class UserManagementForm extends BaseActionFormprivate String userCode;private String userName;private String userStatus;public String getUserCode() return userCode;public void setUserCode(String userCode) this.userCode = userCode;public String getUserName() return userName;public void setUserName(String userName) this.userName = userName;public String getUserStatus() return userStatus;public void setUserStatus(String userStatus) this.userStatus = userStatus;这个文件中的字段是根据自己需要随时进行添加4.2 创建struts的form配置文件src/config/struts/userManagement-formbean.xml创建完成后，必须在src/config/struts/struts-config.xml中的相应位置追加此文件（同上）src/config/struts/struts-config.xml!DOCTYPE struts-config PUBLIC -/Apache Software Foundation/DTD Struts Configuration 1.2/EN /struts/dtds/struts-config_1_2.dtd -省略- -省略-&userManagement-formbean;5创建action配置文件这里的action页面就是action-mapping对象，通过它给定URI以及需要用到的frombean，然后实现页面的跳转src/config/struts/userManagement-action.xml这里的path就是以后用到的请求的URI，name是用到的frombean，现在我们所需要的的UserManagementForm在struts配置中的饿逻辑名是userManagementForm，所以name指定其逻辑名。Forward是页面的跳转，现在我们需要做一个查询主控页面，逻辑名字定义为info（名字最好能定义的明确一点），黄色标记的path就是这个页面对应的jsp，等我们把jsp编辑完后就可以在这添加了。同样，这个配置文件也得在src/config/struts/struts-config.xml中的相应位置追加此文件（同上）src/config/struts/struts-config.xml!DOCTYPE struts-config PUBLIC -/Apache Software Foundation/DTD Struts Configuration 1.2/EN /struts/dtds/struts-config_1_2.dtd -省略- -省略-&userManagement-action;6创建jsp页面6.1 根据Use Case中的页面样式编辑自己的jsp页面WebRoot/userManagement/user.jsp 这里的的action是在struts的action配置中对应的path，即URI，因为在action配置文件中给这个action指定了formbean，所以没有特殊情况就不必要在在这页面指定其它的formbean了。大家注意，这里用蓝色标记的东西都是这个formbean的类文件里定义的，在这里，formbean的作用是数据交互的载体。 标签是定义网格的，它的name元素是指定在grid配置文件中对应的gri配置标签是用于网格上面按钮显示以及触发事件的配置。Jsp页面写好后，就得在刚才写的action配置文件中的forward元素中追加path了src/config/ struts/userManagement-action.xml7创建action文件com/pw/authority/action/UserManagementAction.javapackage com.pw.authority.action;import java.io.IOException;import java.util.List;import javax.servlet.ServletException;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import mons.logging.Log;import mons.logging.LogFactory;import org.apache.struts.action.ActionForm;import org.apache.struts.action.ActionForward;import org.apache.struts.action.ActionMapping;import org.apache.struts.action.ActionMessage;import org.apache.struts.action.ActionMessages;import org.jdom.Document;import org.jdom.output.XMLOutputter;import com.pw.authority.form.UserManagementForm;import com.pw.authority.service.IUserManagementService;import mon.action.BaseAction;import mon.util.GridUtils;import com.pw.model.manager.User;public class UserManagementAction extends BaseAction protected final Log log = LogFactory.getLog(getClass(); public ActionForward unspecified(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException return mapping.getInputForward(); public ActionForward userControl(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException return mapping.findForward(info); public ActionForward userControlList(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException String gridId = request.getParameter(gridId); IUserManagementService ums = (IUserManagementService)this.getBean(userManagementService); UserManagementForm umf = (UserManagementForm)form; List userList = ums.getUserList(umf.getUserCode(); try Document doc = GridUtils.getGridData(gridId, userList); / Grid Name UserManagerControlList if (doc != null) XMLOutputter out = new XMLOutputter(); out.output(doc, response.getWriter(); catch (Exception e) / TODO Auto-generated catch block e.printStackTrace(); return null; 到此，就可以启动服务，打开IE，然后已这个样的形式打开页面了：http:/localhost:8088/pwdev/usermanagement/UserAction.do?p=userControl8创建SQL文件 因为这个是个查询页面，所以必须得与数据库交互，来获得信息，所有就必须写个sql文 src/com/pwdev/sql/userManagementsql.hbm.xml这个文件创建好之后，如果以后还需要写这个模块的其他sql，就可以直接在这个文件中添加就OK了。如果写其他模块的，可以按照这个格式写，放在同一个目录下即可。9. 创建DAO文件这个业务要求是初始进这个页面时，导出user的所有数据，然后可以在页面中对User Code作为查询条件进行模糊查询，根据这些条件写自己的DAO文件src/com/pw/dao/usermanagement/hibernate/ UserManagementDAO.javapackage com.pw.dao.usermanagement.hibernate;import java.util.List; import java.util.HashMap; import java.util.Map;import mon.dao.DaoSupport;import mon.util.StringUtils;import com.pw.dao.gl. IUserManagementDAO;import com.pw.model.manager.User;public class UserManagementDAO extends DaoSupport implements IUserManagementDAOpublic List getAllUserManagement(User form) Map hashMap = new LinkedHashMap(); Conditions condition = new Conditions(); condition.addCondition(U.USER_CODE like :userCode, userCode, StringUtils.strFirstRequired(form.getUserCode(), %); return getDaoTemplate().getObjectsByNativeConditionPagination(getAllUserManagement,hashMap, condition); DAO文件创建好了，创建与它对应的DAO接口文件src/com/pw/dao/usermanagement/ IUserManagementDAO.javapackage com.pw.dao.usermanagement;import java.util.List;import com.pw.model.manager.User; public interface IUserManagementDAOpublic List getAllUserManagement(User form);10. 创建service业务逻辑java文件，并且创建Spring文件10.1 service文件com/pw/authority/service/impl/UserManagementService.javapackage com.pw.authority.service.impl;import com.pw.authority.service.IUserManagementService;public class UserManagementService implements IUserManagementService10.2 接口文件com/pw/authority/service/IUserManagementService.javapackage com.pw.authority.service;public interface IUserManagementService10.3 创建相应的Spring文件src/config/spring/ applicationContext_usermanagement.xml因为在service文件里写业务时必须要用到userManagementDAO类文件，所以必须要依赖注入，注意Spring配置文件，注入内容都在里面。因为在配置文件中对这个service进行了注入，那就必须在service类文件中定义这个注入com/pw/authority/service/impl/UserManagementService.javapackage com.pw.authority.service.impl;import com.pw.authority.service.IUserManagementService;public class UserManagementService implements IUserManagementServiceprivate IUserManagementDAO userManagementDAO;public IUserManagementDAO getUserManagementDAO() return userManagementDAO;public void setUserManagementDAO(IUserManagementDAO userManagementDAO) this.userManagementDAO = userManagementDAO;11. 在service中编辑业务方法这个查询页面的业务很简单，其实就是写个获得grid中的数据的方法com/pw/authority/service/impl/UserManagementService.javapackage com.pw.authority.service.impl;import com.pw.authority.service.IUserManagementService;public class UserManagementService implements IUserManagementServiceprivate IUserManagementDAO userManagementDAO;public IUserManagementDAO getUserManagementDAO() return userManagementDAO;public void setUserManagementDAO(IUserManagementDAO userManagementDAO) this.userManagementDAO = userManagementDAO;public List getUserList(String usercode) User user = new User(); user.setUserCode(usercode);List userlist = userManagementDAO.getAllUserManagement(user);List gridLst = new ArrayList();if (userlist = null) return gridLst;String userCode = ;String userName = ;String branch = ;String department = ;String userType = ;String entityName = ;String userStatus =;String userID = ;String status = login;for( int i=0; iuserlist.size(); i+ )Object o = ( Object ) userlist.get( i );userCode = StringUtils.nullToBlank(o0);userName = StringUtils.nullToBlank(o1);branch = StringUtils.
