**       **本文简单的介绍了如何运用PageHelper插件实现分页功能。

**一、在 pom.xml 中添加如下依赖：**

从下面的地址中查看最新版本的 jar 包

*  [https://oss.sonatype.org/content/repositories/releases/com/github/pagehelper/pagehelper/][https_oss.sonatype.org_content_repositories_releases_com_github_pagehelper_pagehelper]
 *  [http://repo1.maven.org/maven2/com/github/pagehelper/pagehelper/][http_repo1.maven.org_maven2_com_github_pagehelper_pagehelper]

<dependency>
          <groupId>com.github.pagehelper</groupId>
          <artifactId>pagehelper</artifactId>
          <version>5.1.1</version>
        </dependency>

**二、** ** 在 Spring 配置文件中配置拦截器插件，使用 ** **plugins** ** 属性进行配置**

<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
            <property name="dataSource" ref="dataSource"/>
            <property name="plugins">
                <array>
                    <bean class="com.github.pagehelper.PageInterceptor">
                        <property name="properties">
                            
                            <value>
                                offsetAsPageNum=true
                                rowBoundsWithCount=true
                                pageSizeZero=true
                                reasonable=true
                            </value>
                        </property>
                    </bean>
                </array>
            </property>
        </bean>

**三、Dao层实现的方法（切记SQL语句后面不能加分号）**

@Select({
                " select * from answer",
                " where answerId=47"
        })
        List<Answer> selectUserByUserName();

**四、Services层实现的方法，其中PageInfo对象如图所示**

/**
         * 测试分页方法
         */
        public void test(){
            int pageNo = 2;
            int pageSize = 10;
            PageHelper.startPage(pageNo, pageSize);  //startPage是告诉拦截器说我要开始分页了。分页参数是这两个。
            List<Answer> list = iAnswerDao.selectUserByUserName() ;
            PageInfo page = new PageInfo(list);
            System.out.println(page.toString());
    
        }
