用註解方式整合Springboot +SringMVC+ Mybatis

工具：

IntelliJ IDEA 2019.1.3 x64

MySQL

步驟：

1.創建數據庫。創建表tb_wxapp_activitytype

2.創建springboot項目，並勾選引用的依賴，依賴配置pom如下：

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>org.mybatis.spring.boot</groupId>
            <artifactId>mybatis-spring-boot-starter</artifactId>
            <version>2.1.0</version>
        </dependency>

        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <scope>runtime</scope>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>

並在application.properties文件中進行對mybatis的連接配置：

#mysql連接配置
spring.datasource.username=root
spring.datasource.password=root
spring.datasource.url=jdbc:mysql://localhost:3306/thezone3?serverTimezone=UTC&useSSL=false
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver

 

3.創建實體類Tb_wxapp_activitytypeModel。

public class Tb_wxapp_activitytypeModel { 
    private Integer id;
    private String typename;
    private Integer createtime;
    private String  createip;
    private Integer  updatetime;
    private String  updateip;
    private Integer  deletetime;
    private String  deletetip;
    private String  remark;

    /**此處省略get set toString 方法*/
}

4.創建一個接口類Tb_wxapp_activitytype_Interface。作爲Mybatis對數據表的Mapper。

注意：在該類中使用springboot自帶的註解@Mapper，表示該接口爲Mapper，並編寫對應的數據操作。.如下：

package www.zhangxiaosan.top.mapper.Interface;

import org.apache.ibatis.annotations.*;
import www.zhangxiaosan.top.model.Tb_wxapp_activitytypeModel;

import java.util.ArrayList;

@Mapper
public interface Tb_wxapp_activitytype_Interface {
    @Select("select * from tb_wxapp_activitytype")
    ArrayList<Tb_wxapp_activitytypeModel> getAllActivityTypes();

    @Select("select * from tb_wxapp_activitytype where id= #{id} ")
    Tb_wxapp_activitytypeModel getTypeById(Integer id);

    @Select("select * from tb_wxapp_activitytype where typename= #{typename} ")
    Tb_wxapp_activitytypeModel getTypeByTypeName(String typename);

    @Update("update tb_wxapp_activitytype set typename=#{typename},updatetime=#{updatetime},updateip=#{updateip},remark=#{remark} where id=#{id}")
    int updateActivityType(Tb_wxapp_activitytypeModel tb_wxapp_activitytypeModel);

    @Delete("update tb_wxapp_activitytype set deletetime = #{deletetime} ,deleteip = #{deleteip} where id=#{id}")
    int deleteActivityType(Integer id, @Param("deletetime") Integer deletetime,@Param("deleteip") String deleteip);

    @Insert("insert into tb_wxapp_activitytype (typename,createtime,createip,remark) values(#{typename},#{createtime},#{createip},#{remark}) ")
    int insertActivityType(Tb_wxapp_activitytypeModel tb_wxapp_activitytypeModel);

}

5.編寫一個類Tb_wxapp_activitytype_Service。作爲Service層處理邏輯。

注意：此處中使用註解@Service，表示該類爲Service。

如下：

package www.zhangxiaosan.top.service;

import org.springframework.amqp.core.Message;
import org.springframework.amqp.rabbit.annotation.EnableRabbit;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.cache.annotation.CacheEvict;
import org.springframework.cache.annotation.CachePut;
import org.springframework.cache.annotation.Cacheable;
import org.springframework.cache.annotation.Caching;
import org.springframework.stereotype.Service;
import www.zhangxiaosan.top.mapper.Interface.Tb_wxapp_activitytype_Interface;
import www.zhangxiaosan.top.model.Tb_wxapp_activitytypeModel;

import java.util.ArrayList;

@Service
public class Tb_wxapp_activitytype_Service  {

    /**
    * 自動注入，自動注入 Mapper類   
    */
    @Autowired
    Tb_wxapp_activitytype_Interface tb_wxapp_activitytype_interface;


    
}

6.創建一個類Tb_wxapp_activitytype_Controller ，用於接收頁面的 數據。

注意：此處使用註解@Controller，表示該類爲controller控制器類。 

package www.zhangxiaosan.top.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
import www.zhangxiaosan.top.model.Tb_wxapp_activitytypeModel;
import www.zhangxiaosan.top.service.Tb_wxapp_activitytype_Service;

import java.util.ArrayList;
import java.util.Calendar;
import java.util.Date;

@Controller
@RequestMapping(value = "/ActivityTypes")
public class Tb_wxapp_activitytype_Controller {

    /**
    * 自動注入，自動注入Service類
    */
    @Autowired
    Tb_wxapp_activitytype_Service tb_wxapp_activitytype_service;



}

此處省略靜態頁面的創建過程。

到此，框架整合完畢。
