SSH中的Aop使用

1. DAo层:
2. import?org.springframework.orm.hibernate3.support.HibernateDaoSupport;
3. import?org.springframework.orm.hibernate3.*;
4. public?class?UserDao?extends?HibernateDaoSupport?{
5. ????
6. ????public?User?queryUserByID(String?uid){
7. ????????User?user=null;
8. ????????HibernateTemplate?template=this.getHibernateTemplate();
9. ????????user=(User)template.get(User.class,?uid);???????
10. ????????return?user;
11. ????}
12. ????
13. ????
14. ????
15. }
16. bo层:
17. IUser.java:
18. public?interface?IUserBO?{
20. ????public?boolean?login(String?id,String?pwd);
21. ????
22. }
24. UserBo.java:
26. public?class?UserBo?implements?IUserBO?{
27. ????private?UserDao?dao=null;
28. ????private?User?loginUser=null;
29. ????private?String?msg="";
30. ????
31. ????public?void?setDao(UserDao?dao)?{
32. ????????this.dao?=?dao;
33. ????}
35. ????public?boolean?login(String?id,String?pwd){
36. ????????boolean?rtn=false;
37. ????????
38. ????????User?temp=?dao.queryUserByID(id);
39. ????????if(temp!=null){
40. ????????????if(temp.getUserPwd().equals(pwd)){
41. ????????????????this.setLoginUser(temp);????????????????
42. ????????????????this.msg="登陆成功！！！";
43. ????????????????rtn=true;
44. ????????????}else{
45. ????????????????this.msg="密码不正确!!!";
46. ????????????}???????????
47. ????????}else{
48. ????????????this.msg="未找到该用户!!!";
49. ????????}
50. ????????
51. ????????return?rtn;
52. ????}
54. ????public?User?getLoginUser()?{
55. ????????return?loginUser;
56. ????}
58. ????private?void?setLoginUser(User?user)?{
59. ????????this.loginUser=new?User();
60. ????????loginUser.setUserID(user.getUserID());
61. ????????loginUser.setUserName(user.getUserName());
62. ????????loginUser.setUserPwd(user.getUserPwd());
63. ????}
65. ????public?String?getMsg()?{
66. ????????return?msg;
67. ????}
68. ????
69. }
71. 测试bo:
73. public?class?Test?{
75. ????public?static?void?main(String[]?args)?{
76. ????????ApplicationContext?ctx=new?FileSystemXmlApplicationContext?("/WebRoot/WEB-INF/beans.xml");
77. ????????TestDao?dao=(TestDao)?ctx.getBean("testdao");
78. ????????List?list=dao.query();
79. ????????for(Object?obj?:list){
80. ????????????Book?temp=(Book)obj;
81. ????????????System.out.println(temp.getBookName()+":");
82. ????????????Set?set=?temp.getAuthorset();
83. ????????????for(Object?child:set){
84. ????????????????Author?childnode=(Author)child;
85. ????????????????System.out.println(childnode.getAuthorName());
86. ????????????}
87. ????????}
88. ????????
90. ????}
92. }
94. model层?我就省略了
96. util层:使用aop方法后通知的代理机制
98. SafeLogger.java:
99. public?class?SafeLogger?implements?AfterReturningAdvice?{
101. ????public?void?afterReturning(Object?result,?Method?method,?Object[]?args,?Object?target)?throws?Throwable?{
102. ?????????
103. ????????String?methodName=method.getName();
104. ????????
105. ????????if(methodName.equals("login")){
106. ????????
107. ????????????boolean?flag=?Boolean.parseBoolean(result.toString());
108. ????????????if(flag){
109. ????????????????String?uid=?args[0].toString();
110. ????????????????Logger?logger=Logger.getRootLogger();
111. ????????????????logger.warn("用户"+uid+"已登陆");
112. ????????????}
113. ????????}
114. ????}
116. }
118. web层:
119. ActionForm我省略了没什么可说的
120. Action:
122. public?class?LoginAction?extends?Action?{
123. ????
124. ????private?IUserBO?bo;
125. ????
126. ????public?void?setBo(IUserBO?bo)?{
127. ????????this.bo?=?bo;
128. ????}
130. ????public?ActionForward?execute(ActionMapping?mapping,?ActionForm?form,
131. ????????????HttpServletRequest?request,?HttpServletResponse?response)?{
132. ????????//1
133. ????????LoginForm?loginForm?=?(LoginForm)?form;
134. ????????boolean?flag=false;
135. ????????//2
136. ????????if(bo.login(loginForm.getLoginID(),?loginForm.getLoginPwd())){
137. ????????????flag=true;
138. ????????}
139. ????????//3
140. ????????if(flag){
141. ????????????return?mapping.findForward("success");
142. ????????}else{
143. ????????????return?mapping.findForward("failure");
144. ????????}
145. ????????
146. ????}
147. }
150. struts-config.xml配置文件
152. <struts-config>
153. ??<data-sources?/>
154. ??<form-beans?>
155. ????<form-bean?name="loginForm"?type="lee.web.LoginForm"?/>
157. ??</form-beans>
159. ??<global-exceptions?/>
160. ??<global-forwards?/>
161. ??<action-mappings?>
162. ????<action?attribute="loginForm"?input="/login.jsp"?name="loginForm"??path="/login"??scope="request"??type="org.springframework.web.struts.DelegatingActionProxy"?validate="true"?>
163. ??????<forward?name="success"?path="/main.jsp"?/>
164. ??????<forward?name="failure"?path="/error.jsp"?/>
165. ????</action>
168. ??</action-mappings>
170. ??<message-resources?parameter="lee.web.UsersResources"?/>
171. ??<plug-in?className="org.apache.struts.validator.ValidatorPlugIn">
172. ????????<set-property?property="pathnames"?value="/WEB-INF/validator-rules.xml,/WEB-INF/validation.xml"/>
173. ??</plug-in>
174. ??<plug-in?className="org.springframework.web.struts.ContextLoaderPlugIn">
175. ????????<set-property?property="contextConfigLocation"?value="/WEB-INF/beans.xml"?/>
176. ??</plug-in>
177. </struts-config>
179. 最后是spring的配置文件:
