Struts2+Spring3.2+ibatis2.3整合
转自：http://blog.163.com/ppy2790@126/blog/static/1032422412013330105358161/
一、代码目录结构：
二、web.xml配置：（集成struts、spring）

</web-app>
三、spring配置：（整合ibats，配置数据数据库，事务管理，配置ibatis）

五、分层调用：bean-->dao(spring-dao.xml)-->servcie(spring-service.xlm)-->action(spring-action.xml)-->view(jsp)
sqlmap/xxx.xml _|
ibatis的sql配置文件：
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE sqlMap
PUBLIC "-//ibatis.apache.org//DTD SQL Map 2.0//EN"
"http://ibatis.apache.org/dtd/sql-map-2.dtd">
<sqlMap namespace="user">
<select id="findUsers" resultClass="cn.itair.bean.Users">
SELECT
uid,uname,upass
FROM
USERS
</select>
<insert id="save">
INSERT INTO users(uname,upass) VALUES
(#uname#,#upass#)
</insert>
<select id="count" resultClass="java.lang.Integer">
select count(*) as count from
users
</select>
<select id="getAllUser" resultClass="cn.itair.bean.Users" parameterClass="java.util.Map">
<![CDATA[
SELECT uid, uname, upass FROM users limit #start# ,#end#
]]>
</select>
</sqlMap>
六、封装一个ibatis操作的基类，每个dao类从该类继承：
package cn.itair.web.code;
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletContext;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;
import org.apache.log4j.Logger;
import org.apache.struts2.ServletActionContext;
import com.opensymphony.xwork2.ActionSupport;
public class BaseAction extends ActionSupport {
private static final long serialVersionUID = -4025716041310497629L;
private Logger log4j = Logger.getLogger(BaseAction.class);
public String jsonString;
public void outJsonString(String str) {
getResponse().setContentType("text/javascript;charset=UTF-8");
outString(str);
}
public void outString(String str) {
try {
PrintWriter out = getResponse().getWriter();
out.write(str);
} catch (IOException e) {
e.printStackTrace();
log4j.error("out print failed:" + e);
}
}
public void outXMLString(String xmlStr) {
getResponse().setContentType("application/xml;charset=UTF-8");
outString(xmlStr);
}
/**
* 获得request
*
* @return
*/
public HttpServletRequest getRequest() {
return ServletActionContext.getRequest();
}
/**
* 获得response
*
* @return
*/
public HttpServletResponse getResponse() {
return ServletActionContext.getResponse();
}
/**
* 获得session
*
* @return
*/
public HttpSession getSession() {
return getRequest().getSession();
}
/**
* 获得servlet上下文
*
*
*
* @return
*/
public ServletContext getServletContext() {
return ServletActionContext.getServletContext();
}
public String getRealyPath(String path) {
return getServletContext().getRealPath(path);
}
}
七、分页工具类PageUtil:
public class PageUtil {
private int curPage = 0; // 当前页
private int pageSize = 0; // 每页多少行
private int endSize; // 用于not in(select top endSize id)不在多少行内
private int totalRow; // 共多少行
private int totalPage; // 共多少页
public int getStart() {
if (curPage > 1)
return (curPage - 1) * pageSize;
else
return 0;
}
public int getEnd() {
return pageSize;
}
public int getCurPage() {
return curPage;
}
public void setCurPage(int curPage) {
int temp = pageSize * (curPage - 1);
this.setEndSize(temp);
this.curPage = curPage;
}
public int getEndSize() {
return endSize;
}
public void setEndSize(int endSize) {
this.endSize = endSize;
}
public int getPageSize() {
return pageSize;
}
public void setPageSize(int pageSize) {
this.pageSize = pageSize;
}
public int getTotalRow() {
return totalRow;
}
public void setTotalRow(int totalRow) {
totalPage = totalRow / pageSize;
if (totalRow % pageSize > 0)
totalPage = totalPage + 1;
this.totalRow = totalRow;
}
public int getTotalPage() {
return this.totalPage;
}
public String getToolsMenu() {
StringBuffer str = new StringBuffer("");
int next, prev;
prev = curPage - 1;
next = curPage + 1;
if (curPage > 1) {
str
.append("<a href="javascript:void(0)" onclick="document.forms[0].pages.value=1;document.forms[0].submit();">首页</a> ");
} else {
str.append("<a href="javascript:void(0)">首页</a> ");
}
if (curPage > 1) {
str
.append("<a href="javascript:void(0)" onclick='document.forms[0].pages.value="
+ prev
+ ";document.forms[0].submit();'>上页</a> ");
} else {
str.append("<a href="javascript:void(0)">上页</a> ");
}
if (curPage < totalPage) {
str
.append("<a href="javascript:void(0)" onclick='document.forms[0].pages.value="
+ next
+ ";document.forms[0].submit();'>下页</a> ");
} else {
str.append("<a href="javascript:void(0)" >下页</a> ");
}
if (totalPage > 1 && curPage != totalPage) {
str
.append("<a href="javascript:void(0)" onclick='document.forms[0].pages.value="
+ totalPage
+ ";document.forms[0].submit();'>末页</a> ");
} else {
str.append("<a href="javascript:void(0)" >末页</a> ");
}
str.append(" 共" + totalRow + "条记录");
str.append(" 第"+curPage+"页");
str
.append(" 每页<SELECT size=1 name=pagesize onchange='this.form.pages.value=1;this.form.pageSize.value=this.value;this.form.submit();'>");
if (pageSize == 3) {
str.append("<OPTION value=3 selected>3</OPTION>");
} else {
str.append("<OPTION value=3>3</OPTION>");
}
if (pageSize == 10) {
str.append("<OPTION value=10 selected>10</OPTION>");
} else {
str.append("<OPTION value=10>10</OPTION>");
}
if (pageSize == 20) {
str.append("<OPTION value=20 selected>20</OPTION>");
} else {
str.append("<OPTION value=20>20</OPTION>");
}
if (pageSize == 50) {
str.append("<OPTION value=50 selected>50</OPTION>");
} else {
str.append("<OPTION value=50>50</OPTION>");
}
if (pageSize == 100) {
str.append("<OPTION value=100 selected>100</OPTION>");
} else {
str.append("<OPTION value=100>100</OPTION>");
}
str.append("</SELECT>");
str.append("条 分" + getTotalPage() + "页显示 转到");
str
.append("<SELECT size=1 name=Pagelist onchange='this.form.pages.value=this.value;this.form.submit();'>");
for (int i = 1; i < totalPage + 1; i++) {
if (i == curPage) {
str.append("<OPTION value=" + i + " selected>" + i
+ "</OPTION>");
} else {
str.append("<OPTION value=" + i + ">" + i + "</OPTION>");
}
}
str.append("</SELECT>页");
str.append("<INPUT type=hidden value=" + curPage
+ " name="pages" > ");
str.append("<INPUT type=hidden value=" + pageSize
+ " name="pageSize"> ");
return str.toString();
}
}
八、action代码：
public class UsersAction extends BaseAction {
private UserService userService;
private int pages = 1;
private int pageSize = 3;
private String pageBar;
private List<Users> list;
private Users user;
@Override
public String execute() throws Exception {
// TODO Auto-generated method stub
userService.add(user);
return "user";
}
public String doList() throws Exception {
PageUtil page = new PageUtil();
int count = getUserService().getCount();
page.setCurPage(pages);
page.setPageSize(pageSize);
page.setTotalRow(count);
pageBar = page.getToolsMenu();
Map<String, Integer> pageMap = new HashMap<String, Integer>();
pageMap.put("start", page.getStart());
pageMap.put("end", page.getEnd());
list = getUserService().getAllUser(pageMap);
return "list";
}
//getters and setters
}
九、页面代码：
<h4>user information list</h4>
<hr>
<s:form action="userList">
<s:iterator value="#request.list" id="us">
<s:property value="#us.uname"/>
<br/>
</s:iterator>
<hr>
<s:property value="#request.pageBar" escape="false"/>
</s:form>
