【正文】 lumn=roleId/manytomany/set/class3 部門(Department)操作的功能分析(增,刪,改,查), 列出Action方法, ActionForm, 與業(yè)務方法.① DepartmentAction中的方法public ActionForward list(ActionMapping mapping, ActionForm form, HttpServletRequest request,HttpServletResponse response) throws Exception {DepartmentForm deptForm = (DepartmentForm) form。int parentId = ()。Department parent = (parentId)。ListDepartment depts = (parent)。// 準備數(shù)據(depts, depts)。(parent, parent)。return (list)。}public ActionForward tree(ActionMapping mapping, ActionForm form, HttpServletRequest request,HttpServletResponse response) throws Exception {ListDepartment depts = (null)。// 準備數(shù)據(depts, depts)。return (tree)。}public ActionForward saveUI(ActionMapping mapping, ActionForm form, HttpServletRequest request,HttpServletResponse response) throws Exception {DepartmentForm deptForm = (DepartmentForm) form。Department dept = (())。if (dept != null) {(())。(())。(() == null ? 0 : ().getId())。}return (save)。}public ActionForward save(ActionMapping mapping, ActionForm form, HttpServletRequest request,HttpServletResponse response) throws Exception {DepartmentForm deptForm = (DepartmentForm) form。Department parent = (())。Department dept = (())。if (dept == null) {dept = new Department()。}(())。(parent)。(dept)。return (showDepts)。}public ActionForward del(ActionMapping mapping, ActionForm form, HttpServletRequest request,HttpServletResponse response) throws Exception {DepartmentForm deptForm = (DepartmentForm) form。(())。return (showDepts)。}② DepartmentForm 的代碼：public class DepartmentForm extends ActionForm {private int id。private String name。private int parentId。public int getId() {return id。}public String getName() {return name。}public int getParentId() {return parentId。}public void setId(int id) { = id。}public void setName(String name) { = name。}public void setParentId(int parentId) { = parentId。}}③ 業(yè)務方法：public Department getDept(int id) {return (Department) getSession().get(, id)。}@SuppressWarnings(unchecked)public ListDepartment findDepts(Department parent) {if (parent == null) {return getSession().createQuery(//from Department d where =null)//.list()。} else {return getSession().createQuery(//from Department d where =?)//.setParameter(0, parent)//.list()。}}public void save(Department dept) {getSession().saveOrUpdate(dept)。}public void delDept(int id) {Department dept = (Department) getSession().get(, id)。if (dept != null) {getSession().delete(dept)。}}4 使用過濾器控制事務(CloseSessionFilter).代碼如下：public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)throws IOException, ServletException {try {((HttpServletRequest)request).setCharacterEncoding(utf8)。(request, response)。} catch (Exception e) {JbpmContext jbpmContext = ().getCurrentJbpmContext(false)。if (jbpmContext != null) {()。}throw new ServletException(e)。} finally {JbpmContext jbpmContext = ().getCurrentJbpmContext(false)。if (jbpmContext != null) {()。}}}16 / 16
