一、配置文件：

1、pom.xml依赖文件：

    	</dependencies>
    </project>

2、spring.xml配置文件:

<?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans"
    	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"

    	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
    		http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd
    		http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.3.xsd">

    			expression="org.springframework.stereotype.Controller" />
    	</context:component-scan>
    
    	<context:property-placeholder location="classpath:jdbc.properties" />
    
    	<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"

    	</bean>
    
    	
    	<tx:annotation-driven transaction-manager="transactionManager" />
    
    </beans>

引用的数据库参数jdbc.properties文件：

jdbc.driverClassName=oracle.jdbc.driver.OracleDriver
    jdbc.url=jdbc:oracle:thin:@172.16.130.35:1521:orcl
    jdbc.username=wtyy1

    		<property name="maxInMemorySize" value="40960" />
    	</bean>
    
    
    </beans>

4、web.xml:

<?xml version="1.0" encoding="UTF-8"?>
    <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    	xmlns="http://java.sun.com/xml/ns/javaee"
    	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"

    		<filter-name>characterEncodingFilter</filter-name>
    		<url-pattern>/*</url-pattern>
    	</filter-mapping>
    
    </web-app>

二、测试：

1、实体类：

package com.iflytek.domain;
    
    import java.io.Serializable;
    
    public class Blog implements Serializable{
    
    	private Integer id;
    	
    	private String title;
    	
    	private String body;
    
    	public Integer getId() {
    		return id;
    	}
    
    	public void setId(Integer id) {
    		this.id = id;
    	}
    
    	public String getTitle() {
    		return title;
    	}
    
    	public void setTitle(String title) {
    		this.title = title;
    	}
    
    	public String getBody() {
    		return body;
    	}
    
    	public void setBody(String body) {
    		this.body = body;
    	}
    	
    	
    }

2、dao包：

（1、）BlogMapper.java：

package com.iflytek.dao;
    
    import org.springframework.stereotype.Repository;
    
    import com.iflytek.domain.Blog;
    
    @Repository
    public interface BlogMapper {
    	public Blog findById(int id);
    }

（2、）BlogMapper.xml：

<?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.iflytek.dao.BlogMapper">
    	
    	<select id="findById" resultType="Blog">
    		select * from t_blog where id = #{id}
    	</select>
    </mapper>

3、service:

package com.iflytek.service;
    
    import javax.annotation.Resource;
    
    import org.springframework.stereotype.Service;
    
    import com.iflytek.dao.BlogMapper;
    import com.iflytek.domain.Blog;
    
    @Service
    public class BlogService {
    
    	@Resource
    	private BlogMapper blogMapper;
    	
    	public Blog findBlog(int id) {
    		return blogMapper.findById(id);
    	}
    
    }

4、controller:

package com.iflytek.controller;
    
    import javax.annotation.Resource;
    
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.GetMapping;
    import org.springframework.web.bind.annotation.RequestAttribute;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.ResponseBody;
    
    import com.iflytek.domain.Blog;
    import com.iflytek.service.BlogService;
    
    @Controller
    public class BlogController {
    	
    	@Resource
    	private BlogService blogService;
    
    	@GetMapping("/getById")
    	@ResponseBody
    	public Blog findBlog(int id) {
    		Blog b= blogService.findBlog(id);
    		System.out.println(b);
    		return b;
    	}
    }
