• Mybatis分页插件


    springmvc与spring-mybatis的配置与普通的SSM项目配置是一样的,

    只不过在spring-mybatis中需要加入分页拦截器

    一、spring-mybatis.xml的配置

     1 <?xml version="1.0" encoding="UTF-8"?>
     2 <beans xmlns="http://www.springframework.org/schema/beans"
     3     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
     4     xmlns:tx="http://www.springframework.org/schema/tx"
     5     xsi:schemaLocation="http://www.springframework.org/schema/beans
     6 http://www.springframework.org/schema/beans/spring-beans-4.3.xsd
     7 http://www.springframework.org/schema/context
     8 http://www.springframework.org/schema/context/spring-context-4.3.xsd
     9 http://www.springframework.org/schema/tx
    10 http://www.springframework.org/schema/tx/spring-tx-4.3.xsd
    11 ">
    12     <!-- 自动扫描包 -->
    13     <context:component-scan base-package="com.llh.*" />
    14     
    15     <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> 
    16         <property name="driverClassName" value="com.mysql.jdbc.Driver"></property> 
    17         <property name="url" value="jdbc:mysql://localhost:3306/pagetext"></property> 
    18         <property name="username" value="root"></property>
    19         <property name="password" value="123456"></property>
    20     </bean>
    21     <!-- mybatis配置 -->
    22     <bean class="org.mybatis.spring.SqlSessionFactoryBean">
    23         <property name="dataSource" ref="dataSource"></property>
    24         <!-- 分页拦截器 -->
    25         <property name="plugins">
    26             <array>
    27                 <bean class="com.github.pagehelper.PageInterceptor">
    28                     <property name="properties">
    29                         <value>
    30                             helperDialect=mysql
    31                             rowBoundsWithCount=true
    32                             supportMethodsArguments=true
    33                             reasonable=true
    34                         </value>
    35                     </property>
    36                 </bean>
    37             </array>
    38         </property>
    39 
    40     </bean>
    41     <!-- 映射配置器 -->
    42     <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
    43         <property name="basePackage" value="com.llh.dao"></property>
    44     </bean>
    45     <!-- 事务管理器 -->
    46     <bean id="transactionManager"
    47         class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
    48         <property name="dataSource" ref="dataSource"></property>
    49     </bean>
    50 
    51     <!-- 开启事务注解 -->
    52     <tx:annotation-driven />
    53 
    54 </beans>

    二、在Controller里直接调用即可

     1 package com.llh.controller;
     2 
     3 import java.util.List;
     4 
     5 import javax.annotation.Resource;
     6 import javax.servlet.http.HttpSession;
     7 
     8 import org.springframework.context.annotation.Scope;
     9 import org.springframework.stereotype.Controller;
    10 import org.springframework.web.bind.annotation.RequestMapping;
    11 import org.springframework.web.bind.annotation.ResponseBody;
    12 
    13 import com.github.pagehelper.PageHelper;
    14 import com.github.pagehelper.PageInfo;
    15 import com.llh.entity.Student;
    16 import com.llh.service.StudentService;
    17 
    18 import net.sf.json.JSONArray;
    19 
    20 @Controller
    21 @Scope("prototype")
    22 public class StudentController {
    23 
    24     @Resource
    25     private StudentService studentService;
    26     @RequestMapping(value="selectAllStudent",produces="text/html;charset=utf-8")
    27     private @ResponseBody String selectAllStudent(HttpSession session,int pageCode,int pageSize){
    28         
    29         PageHelper.startPage(pageCode, pageSize);
    30         
    31         List<Student> slist =  studentService.selectAll();
    32         PageInfo<Student> spi = new PageInfo<Student>(slist);
    33         int count = (int) spi.getTotal();
    34         JSONArray json = JSONArray.fromObject(slist);
    35         String str="{"total":"+count+","rows":"+json.toString()+"}";
    36         return str;
    37     }
    38     
    39 }

    说明一下,这里使用到的是bootstrap前端,有需要的话可以查看本人的博客园首页,有bootstrap-fileinput上传的实例

    51     };
    52     return params;
    53 }
    54 </script>
