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"
	xmlns:tx="http://www.springframework.org/schema/tx"
	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">


	<context:component-scan base-package="com.iflytek">

	</bean>

	<!--5.开启注解进行事务管理 transaction-manager：引用上面定义的事务管理器 -->
	<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
jdbc.password=wtyy1


hibernate.dialect=org.hibernate.dialect.Oracle10gDialect
hibernate.hbm2ddl.auto=update
hibernate.show_sql=true
hibernate.format_sql=true

3、springmvc.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"

	</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"

	id="WebApp_ID" version="3.0">

	<!-- spring配置文件的路径 -->
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath:spring.xml</param-value>
	</context-param>

	<servlet>
		<servlet-name>dispatcher</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<init-param>
			<param-name>contextConfigLocation</param-name>

	</filter>
	<filter-mapping>
		<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;
	}
}
