SpringBoot 整合Mybatis3.x註解開發

1. 使用starter

• maven倉庫地址

2. 加入依賴（可以使用 https://start.spring.io/ 下載）

<!-- starter -->
<dependency>
	<groupId>org.mybatis.spring.boot</groupId>
	<artifactId>mybatis-spring-boot-starter</artifactId>
	<version>1.3.1</version>
</dependency>

<!-- MySQL的JDBC驅動包 -->
<dependency>
	<groupId>mysql</groupId>
	<artifactId>mysql-connector-java</artifactId>
	<scope>runtime</scope>
</dependency>

<!-- 引入第三方數據源 -->
<dependency>
	<groupId>com.alibaba</groupId>
	<artifactId>druid</artifactId>
	<version>1.1.6</version>
</dependency>

3. 加入配置文件

# 可以自動識別
# spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/movie?useUnicode=true&characterEncoding=utf-8&useSSL=false
spring.datasource.username=root
spring.datasource.password=password
# 如果不適用默認的數據源（com.zaxxer.hikari.HikariDataSource）
spring.datasource.type=com.alibaba.druid.pool.DruidDataSource

4. 啓動類增加mapper掃描

@MapperScan("com.shadowolf.base_project.mapper")

5. 開發mapper

參考語法

• 例子

  package com.shadowolf.base_project.mapper;
  
  import com.shadowolf.base_project.domain.User;
  import org.apache.ibatis.annotations.*;
  
  import java.util.List;
  
  public interface UserMapper {
  
      @Insert("INSERT INTO user(name, phone, create_time, age) VALUES(#{name}, #{phone}, #{createTime}, #{age})")
      // 保存對象，獲取數據庫自增id
      @Options(useGeneratedKeys = true, keyProperty = "id", keyColumn = "id")
      int insert(User user);
  
      @Select("SELECT * FROM user")
      @Results({
              @Result(column = "create_time", property = "createTime")
      })
      List<User> getAll();
  
      @Select("SELECT * FROM user WHERE id = #{id}")
      @Results({
              @Result(column = "create_time", property = "createTime")
      })
      User findById(Long id);
  
      @Update("UPDATE user SET name = #{name} where id = #{id}")
      void update(User user);
  
      @Delete("DELETE FROM user WHERE id = #{id}")
      void delete(Long id);
  
  }
