分页

在generatorConfig.xml中加入：

<plugin type="org.mybatis.generator.plugins.MySQLPaginationPlugin">plugin>

分页源代码

下载mybaits-generator源下载，然后在org.mybatis.generator.plugins路径下新建一下类：MySQLPaginationPlugin
然后编辑后放到eclipse->plugin下的 org.mybatis.generator.core_1.3.4.201608190045.jar包里即可。
这样做的好处是，如果你自己写的话，你需要打成jar包，然后再在本地仓库引用，比较麻烦，否则你会抛无法实例化对象的错误。错误如下所示：

生成的效果代码

如果使用page对象进行分页，需要加入page类

import java.io.Serializable;

public final class Page implements Serializable {
     

    /**
     * 默认的序列化版本 id.
     */
    private static final long serialVersionUID = 1L;
    /**
     * 分页查询开始记录位置.
     */
    private int begin;
    /**
     * 分页查看下结束位置.
     */
    private int end;
    /**
     * 每页显示记录数.
     */
    private int length = 20;
    /**
     * 查询结果总记录数.
     */
    private int totalRecords;
    /**
     * 当前页码.
     */
    private int pageNo;
    /**
     * 总共页数.
     */
    private int pageCount;

    public Page() {
    }

    /**
     * 构造函数.
     *
     * @param begin
     * @param length
     */
    public Page(int begin, int length) {
        this.begin = begin;
        this.length = length;
        this.end = this.begin + this.length;
        this.pageNo = (int) Math.floor((this.begin * 1.0d) / this.length) + 1;
    }

    /**
     * @param begin
     * @param length
     * @param count
     */
    public Page(int begin, int length, int totalRecords) {
        this(begin, length);
        this.totalRecords = totalRecords;
    }

    /**
     * 设置页数，自动计算数据范围.
     *
     */
    public Page(int pageNo) {
        this.pageNo = pageNo;
        pageNo = pageNo > 0 ? pageNo : 1;
        this.begin = this.length * (pageNo - 1);
        this.end = this.length * pageNo;
    }

    public int getBegin() {
        return begin;
    }

    public int getEnd() {
        return end;
    }

    public void setEnd(int end) {
        this.end = end;
    }

    public void setBegin(int begin) {
        this.begin = begin;
        if (this.length != 0) {
            this.pageNo = (int) Math.floor((this.begin * 1.0d) / this.length) + 1;
        }
    }

    public int getLength() {
        return length;
    }

    public void setLength(int length) {
        this.length = length;
        if (this.begin != 0) {
            this.pageNo = (int) Math.floor((this.begin * 1.0d) / this.length) + 1;
        }
    }

    public int getTotalRecords() {
        return totalRecords;
    }

    public void setTotalRecords(int totalRecords) {
        this.totalRecords = totalRecords;
        this.pageCount = (int) Math.floor((this.totalRecords * 1.0d) / this.length);
        if (this.totalRecords % this.length != 0) {
            this.pageCount++;
        }
    }

    public int getPageNo() {
        return pageNo;
    }

    public void setPageNo(int pageNo) {
        this.pageNo = pageNo;
        pageNo = pageNo > 0 ? pageNo : 1;
        this.begin = this.length * (pageNo - 1);
        this.end = this.length * pageNo;
    }

    public int getPageCount() {
        if (pageCount == 0) {
            return 1;
        }
        return pageCount;
    }

    public void setPageCount(int pageCount) {
        this.pageCount = pageCount;
    }

    @Override
    public String toString() {
        final StringBuilder builder = new StringBuilder("begin=").append(begin).append(", end=")
                .append(end).append(", length=").append(length).append(", totalRecords=").append(
                        totalRecords).append(", pageNo=").append(pageNo).append(", pageCount=")
                .append(pageCount);
        return builder.toString();
    }
}

idea

pom.xml 中配置build

<build>
        <plugins>
            <plugin>
                <groupId>org.springframework.bootgroupId>
                <artifactId>spring-boot-maven-pluginartifactId>
            plugin>
            <plugin>
                <groupId>org.mybatis.generatorgroupId>

覆盖jar

用上面csdn资源上下载的 mybatis-generator-core-1.3.4.jar
覆盖 C:\Users\Administrator.m2\repository\org\mybatis\generator\mybatis-generator-core\1.3.4\mybatis-generator-core-1.3.4.jar （如果是用的idea默认的maven的话）

运行
