博客介绍了信息技术相关的配置流程，包括maven配置文件，配置bean，涉及dept contoller文件、mapper文件，还说明了基本xml mapper文件的配置，最后是myitbit配置文件的配置。

1.maven 配置文件：

<dependencies>
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-jdbc</artifactId>
		</dependency>
		<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>2.0.0</version>
		</dependency>


		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-configuration-processor</artifactId>
			<optional>true</optional>
		</dependency>

		<dependency>
			<groupId>com.alibaba</groupId>
			<artifactId>druid</artifactId>
			<version>1.1.8</version>
		</dependency>

		<dependency>
			<groupId>mysql</groupId>
			<artifactId>mysql-connector-java</artifactId>
			<scope>runtime</scope>
			<version>5.1.46</version>
		</dependency>
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-test</artifactId>
			<scope>test</scope>
		</dependency>
	</dependencies>

	<build>
		<plugins>
			<plugin>
				<groupId>org.springframework.boot</groupId>
				<artifactId>spring-boot-maven-plugin</artifactId>
			</plugin>
		</plugins>
	</build>

2.配置bean:

public class Dept {

    private Integer id;

    private String departmentName;

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getDepartmentName() {
        return departmentName;
    }

    public void setDepartmentName(String departmentName) {
        this.departmentName = departmentName;
    }
}

dept contoller 文件：

  @Autowired
    private DeptMapper deptMapper;

    @RequestMapping("/findOne/{id}")
    public Dept findOne(@PathVariable("id") Integer id){
        return deptMapper.findOne(id);
    }

    @RequestMapping("/list")
    public List<Dept> list() {
        return deptMapper.list();
    }

    @RequestMapping("/save")
    public int save(Dept dept) {
        deptMapper.save(dept);
        return dept.getId();
    }

mappper 文件：

@Mapper
public interface DeptMapper {


    Dept findOne(Integer id);

    List<Dept> list();

    int save(Dept dept);

}

配置一个基本的xml mapper 文件：

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
        PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">

<mapper namespace="com.tuling.mapper.DeptMapper">
    <select id="findOne" parameterType="Integer" resultType="com.tuling.bean.Dept">
        select * from department where id = #{id}
    </select>

    <select id="list" resultType="com.tuling.bean.Dept">
        select * from department
    </select>

    <insert id="save" parameterType="com.tuling.bean.Dept" keyProperty="id" useGeneratedKeys="true">
        insert into department(department_name) values(#{departmentName})
    </insert>
</mapper>

5.最后配置myitbit 的配置文件：

spring:
  datasource:
      druid:
        username: root
        password: 123456
        jdbcUrl: jdbc:mysql://47.104.128.12:3306/tuling-vip
        driverClassName: com.mysql.jdbc.Driver
        initialSize: 5
        minIdle: 5
        maxActive: 20
        maxWait: 60000
        timeBetweenEvictionRunsMillis: 60000
        minEvictableIdleTimeMillis: 300000
        validationQuery: SELECT 1 FROM DUAL
        testWhileIdle: true
        testOnBorrow: false
        testOnReturn: false
        poolPreparedStatements: true
        filters: stat,wall #\u914D\u7F6E\u8FC7\u6EE4\u5668
        maxPoolPreparedStatementPerConnectionSize: 20
        useGlobalDataSourceStat: true
        connectionProperties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=500

#\u914D\u7F6Emybaits
mybatis:
  configuration:
    map-underscore-to-camel-case: true
  mapper-locations: classpath:/mybatis/mapper/*.xml
