插件类

public class PaginationPlugin extends PluginAdapter {


    public boolean validate(List<String> list) {
        return true;
    }

    /**

                                              IntrospectedTable introspectedTable) {

        PrimitiveTypeWrapper integerWrapper = FullyQualifiedJavaType.getIntInstance()
                .getPrimitiveTypeWrapper();

以上工程打好jar 打完之后

Dfile 文件位置
DgroupId
DartifactId 不用说了

mvn install:install-file -Dfile=C:\\pagePulgin-1.0.jar -DgroupId=com.systp -DartifactId=pagePulgin -Dversion=1.0 -Dpackaging=jar

然后在项目中添加mybatis-generator 配置好xml之后 在pom加上

 <plugins>
            <plugin>

                <groupId>org.mybatis.generator</groupId>
                <artifactId>mybatis-generator-maven-plugin</artifactId>

                </configuration>
                <dependencies>
                    <dependency>
                        <groupId>mysql</groupId>
                        <artifactId>mysql-connector-java</artifactId>
                        <version>5.1.34</version>
                    </dependency>
                    <dependency>

                        <artifactId>pagePulgin</artifactId>
                        <version>1.0</version>
                    </dependency>
                </dependencies>


            </plugin>
            <plugin>

                <artifactId>mybatis-generator-maven-plugin</artifactId>

                <dependencies>

                <configuration>
                    <overwrite>true</overwrite>
                </configuration>
            </plugin>

com.systp pagePulgin 是我自己打好的jar 加入之后在通过mybatis-generator重新生成，生成之后就自带分页功能了
