```java
package com.weir.quarkus.mybatis;

import java.util.Date;

import com.baomidou.mybatisplus.extension.activerecord.Model;

public class Users extends Model<Users> {
	public Integer id;
    public Date createDate;
    public String email;
    public String userName;
    public String userPwd;
    public String idStr;
    public String profileImageUrl;

}

```
```java
package com.weir.quarkus.mybatis;
import org.apache.ibatis.annotations.Delete;
import org.apache.ibatis.annotations.Insert;
import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.annotations.Param;
import org.apache.ibatis.annotations.Select;

import com.baomidou.mybatisplus.core.mapper.BaseMapper;

@Mapper
public interface UserMapper extends BaseMapper<Users> {

@Select("SELECT * FROM USERS WHERE id = #{id}")
    Users getUser(Integer id);

@Insert("INSERT INTO USERS (id, name) VALUES (#{id}, #{name})")
    Integer createUser(@Param("id") Integer id, @Param("name") String name);

@Delete("DELETE FROM USERS WHERE id = #{id}")
    Integer removeUser(Integer id);
}
```
```java
package com.weir.quarkus.mybatis;

import javax.inject.Inject;
import javax.ws.rs.Consumes;
import javax.ws.rs.DELETE;
import javax.ws.rs.FormParam;
import javax.ws.rs.GET;

public class ExampleResource {

@GET
    @Produces(MediaType.TEXT_PLAIN)
    public String hello() {
        return "Hello RESTEasy";
    }
    
    @Inject
    UserMapper userMapper;

@Path("/user/{id}")
    @GET
    @Produces(MediaType.APPLICATION_JSON)
    public Users getUser(@PathParam("id") Integer id) {
        return userMapper.getUser(id);
    }
    @Path("/selectById/{id}")
    @GET
    @Produces(MediaType.APPLICATION_JSON)
    public Users get(@PathParam("id") Integer id) {
    	return userMapper.selectById(id);
    }

@Path("/user")
    @POST
    @Produces(MediaType.TEXT_PLAIN)
    @Consumes(MediaType.APPLICATION_FORM_URLENCODED)
    public Integer createUser(@FormParam("id") Integer id, @FormParam("name") String name) {
        return userMapper.createUser(id, name);
    }

@Path("/user/{id}")
    @DELETE
    @Produces(MediaType.TEXT_PLAIN)
    public Integer removeUser(@PathParam("id") Integer id) {
        return userMapper.removeUser(id);
    }
    
    @Path("/user/page/{page}/{pageSize}")
    @GET
    public Page<Users> list(@PathParam("page") Integer page,@PathParam("pageSize") Integer pageSize) {
		return userMapper.selectPage(new Page<Users>(page, pageSize), null);
	}
}
```
最关键的开启mybatis-plus的分页拦截器
```java
package com.weir.quarkus.mybatis;

import javax.enterprise.context.ApplicationScoped;
import javax.enterprise.event.Observes;
import javax.inject.Inject;

import org.apache.ibatis.session.SqlSessionFactory;

import com.baomidou.mybatisplus.extension.plugins.MybatisPlusInterceptor;
import com.baomidou.mybatisplus.extension.plugins.inner.PaginationInnerInterceptor;

import io.quarkus.runtime.Startup;
import io.quarkus.runtime.StartupEvent;

@ApplicationScoped
@Startup
public class BeanConfig {

@Inject
    SqlSessionFactory sqlSessionFactory;

void startup(@Observes StartupEvent event) {
        MybatisPlusInterceptor interceptor = new MybatisPlusInterceptor();
        interceptor.addInnerInterceptor(new PaginationInnerInterceptor());
        sqlSessionFactory.getConfiguration().addInterceptor(interceptor);
    }
}
```
好了启动就可以了，推荐注解形式来写sql，当然用mp很多sql就不用写了，分页也有了，也不用再加入第三方的分页插件，所以基本可以使用了。
