MyBatis实现拦截器分页功能

1.原理

• 在mybatis使用拦截器（interceptor），截获所执行方法的sql语句与参数。
  
  （1）修改sql的查询结果：将原sql改为查询count(*) 也就是条数
  
  （2）将语句sql进行拼接 limit(MySql)或rownum(Oracle)语句达到分页效果
• 制作分页Page类，需要分页的bean继承分页Page类。
• jsp界面通过Page类的属性参数实现对页数控制。

2.具体步骤

（1）首先创建PageBean

（2）配置分页使用的拦截器实现Interceptor接口，重写其抽象方法

@Intercepts({ @Signature(type = StatementHandler.class, method = "prepare", args = { Connection.class }),
        @Signature(type = ResultSetHandler.class, method = "handleResultSets", args = { Statement.class }) })
public class PageInterceptor implements Interceptor {

@Intercepts注解表示被会被拦截的类和方法参数

//SELECT_ID 根据被捕获的方法判断是否需要进行分页 如果方法名含有Page则进行分页
private static final String SELECT_ID = "Page";
//在intercept方法中获取mybatis.xml中的property属性值为PageCount赋值
private Properties properties;
//通过PageBean对象获取Count值的where条件后参数
private PageBean pageBean;

1. 拦截器的主方法则是具体功能的实现，主要做的事：

• 判断被拦截的方法是否需要进行分页

• 需要分页则截取sql语句，截取条件并拼接成查询条数，也就是将

    select * from user    ---->  select count(*) from user

• 获取数据库连接对象，并执行拼接好的count(*)获取条数Sql语句获取数据库条数 ，并将值存到设计好的PageBean对象中

//获取数据库连接对象
Connection connection = (Connection) invocation.getArgs()[0];
//执行countSql语句 并获得Count值 为PageBean的totalCount赋值
PreparedStatement countStmt = null;
ResultSet rs = null;
int totalCount = 0;
try {
countStmt = connection.prepareStatement(countSql);
    rs = countStmt.executeQuery();
if (rs.next()) {
    totalCount = rs.getInt(1);
}
} catch (SQLException e) {
    System.out.println("Ignore this exception" + e);
} finally {
try {
    rs.close();
    countStmt.close();
} catch (SQLException e) {
    System.out.println("Ignore this exception" + e);
    }
}

• 将原sql语句增加limit a,b a为查询结果第一条，b为所查询的条数

public String concatPageSql(String sql, PageBean pageBean) {
        StringBuffer sb = new StringBuffer();
        sb.append(sql);
        sb.append(" limit ").append(pageBean.getPageLimit()).append(" ,").append(pageBean.getPageCount());
        return sb.toString();
    }

• 将拦截修改好的sql语句传递给dao层执行的方法 并返回对应的结果

//将处理好的SQL语句绑定
String pageSql = concatPageSql(sql, pageBean);
//将修改好的sql语句返回给方法
metaStatementHandler.setValue("delegate.boundSql.sql", pageSql);

• 退出拦截器，开始执行dao层方法，执行sql语句进行数据处理

//执行dao层方法
return invocation.proceed();

Controller中配置 接收参数与返回参数

• 参数为PageBean的子类对象–接收由JSP中传入的分页数据信息–模糊查询的参数等等
• 而参数在dao层方法完成后，会在拦截器中对其分页数据进行赋值–也就是经过拦截器处理后，对象的数据增加了
• 以User类为例

@RequestMapping("/selectLikeUser.do")
    //参数为user 而mav.addObject("pageBean", user); 也是user，这是拦截器有对user进行分页信息赋值
    public ModelAndView selectPageLikeAllUser(User user){
        //执行的顺序Service-->拦截器（修改sql语句，注入分页参数）-->Dao方法-->返回结果
        //所以有两个值 ① 分页的数据（当前页，总页数等数据）在user对象中
        //           ② 保存数据的集合userList
        List<User> userList=this.userService.selectPageLikeAllUser(user);
        ModelAndView mav=new ModelAndView();
        mav.addObject("userList", userList);
        //对应的前台Jsp界面
        mav.setViewName("userList");
        //将分页数据保存
        mav.addObject("pageBean", user);
        return mav;
    }

前台Jsp界面

- 翻页需要的button模块

<div class="div_input">
    //分页需要用到的参数有JS对应的方法进行表单提交时传递参数 而limtr 从0开始，后台执行sql语句 limit 0，每页的条数
    //每次点击下一页 变化的都是limit 前面的参数 limit 参数*条数，条数
    //第一页 limit 0*2,2
    //第二页 limit 1*2,2
    //第三页 limit 2*2,2 …………
    <input type="button" class="input_scan" value="首页" onclick="page(0)"/>
    //判断上一页的方法，当表单无上一页是 当前input会被隐藏
    <c:if test="${pageBean.previous}">
        <input type="button" class="input_scan" value="上页" onclick="page(${pageBean.pageNo - 1})"/>
    </c:if>
    //判断下一页的方法，当前为最大页时，input隐藏
    <c:if test="${pageBean.next}">
        <input type="button" class="input_scan" value="下页" onclick="nextPage(${pageBean.pageNo + 1},${pageBean.totalPage})"/>
    </c:if>
    <input type="button" class="input_scan" value="末页" onclick="page(${pageBean.totalPage -1})"/>
    <span class="span_text">跳到第</span>
        <input type="text" class="input_text" name="pageNo" id="pageID"/>
    <span class="span_text">页</span>
        <input type="button" class="input_scan" value="跳转" onclick="pageSubmit(${pageBean.totalPage})"/>
</div>

• 对应的JS方法

//每一次表单的提交，在controller中捕获的都是pageID的那个type='text'的那个文本框
//方法中的逻辑判断则是为了避免一些提交bug，保证pageID的文本框中数值显示正常以及跳转按钮等等
<script type="text/javascript">
function page(pageArg){
    var myform = document.getElementById("myform");
    var pageNo = document.getElementById("pageID");
    pageNo.value = pageArg;
    if(pageArg!=-1){
        myform.submit();
    }else{
        pageNo.value ="";
    }

}
function pageSubmit(pageArg){
    var myform = document.getElementById("myform");
    var pageNo = document.getElementById("pageID");
    if(pageNo.value-1 < pageArg){
        pageNo.value=Number(pageNo.value)-1;
        if(pageNo.value>-1){
            myform.submit();
        }else{
            pageNo.value="";
        }
    }
}
function nextPage(pageArg,totalPage){
    var myform = document.getElementById("myform");
    var pageNo = document.getElementById("pageID");
    pageNo.value = pageArg;
    if(pageArg<totalPage)
        myform.submit();
}
</script>

下面为完整代码

**

• 拦截器中，因为模糊查询，所以多了一些判断参数的方法，以及为sql语句的参数赋值的过程，仅供参考

• PageBean为对应的分页model类，而selectInfo为模糊查询参数，在拦截器中会使用此参数在查询count条数时，修改参数
