    <artifactId>jackson-core</artifactId>  
    <version>2.4.4</version>  
</dependency>
</dependencies>

三.配置swagger2

@EnableWebMvc  
@EnableSwagger2  
@ComponentScan(basePackages = {"com.zc.web.controller"})  
@Configuration  
public class SwaggerApiConfig extends WebMvcConfigurationSupport{  

    @Bean  
    public Docket createRestApi() {  
    return new Docket(DocumentationType.SWAGGER_2)  
            .apiInfo(apiInfo())  
            .select()  
            .apis(RequestHandlerSelectors.basePackage("com.zc.web.controller"))  
            .paths(PathSelectors.any())  
            .build();  
    }  

    private ApiInfo apiInfo() {  
        return new ApiInfoBuilder()  
            .title("Spring 中使用Swagger2构建RESTful APIs")  
            .termsOfServiceUrl("")  
            .contact(new Contact("zc", "", "admin@qq.com")  )
            .version("1.1")  
            .build();  
    }  
}

四.创建配置文件
1 点击项目右键->source folder->创建resources文件夹
2 点击resources右键->folder->创建config文件夹
3 新建jdbc.properties配置文件

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNull&allowMultiQueries=true
jdbc.username=root  
jdbc.password=root

4 新建log4j.properties配置文件

log4j.rootLogger=debug, console, info, error, timer_info_log, timer_error_log

#Output to console(控制台打印)
log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.console.Target=System.out
log4j.appender.console.layout=org.apache.log4j.PatternLayout
log4j.appender.console.layout.ConversionPattern=%p %d{yyyy-MM-dd HH:mm:ss} %t %C.%M %L-line %m%n

#Output to file(根据时间输出日志到文件)
log4j.appender.timer_info_log=org.apache.log4j.DailyRollingFileAppender  
log4j.appender.timer_info_log.Append=true  
log4j.appender.timer_info_log.File=${webapp.root}WEB-INF/logfiles/timer_info/timer_info
log4j.appender.timer_info_log.DatePattern='_'yyyy-MM-dd-HH-mm'.log'
log4j.appender.timer_info_log.Threshold=INFO
log4j.appender.timer_info_log.layout=org.apache.log4j.PatternLayout  
log4j.appender.timer_info_log.layout.ConversionPattern=%d - %c [%t] %-5p %c %x %l - %m%n

log4j.appender.timer_error_log=org.apache.log4j.DailyRollingFileAppender  
log4j.appender.timer_error_log.Append=true  
log4j.appender.timer_error_log.File=${webapp.root}WEB-INF/logfiles/timer_error/timer_error
log4j.appender.timer_error_log.DatePattern='_'yyyy-MM-dd-HH-mm'.log'
log4j.appender.timer_error_log.Threshold=error
log4j.appender.timer_error_log.layout=org.apache.log4j.PatternLayout  
log4j.appender.timer_error_log.layout.ConversionPattern=%d - %c [%t] %-5p %c %x %l - %m%n

4 配置spring.xml

<?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"

    <property name="maxActive" value="20" />
    <property name="maxIdle" value="10" />
    <property name="maxWait" value="10000" />
    <property name="defaultAutoCommit" value="false" />     
</bean>

<!-- mybatis的配置文件 -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
    <property name="dataSource" ref="dataSource"></property>
    <property name="mapperLocations" value="classpath:mybatis/*.xml"></property>
</bean>

<!-- spring与mybatis整合配置，扫描所有dao -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
    <property name="basePackage" value="com.zc.dao"></property>
</bean>
</beans>

5 配置spring-mvc.xml

<?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"

       http://www.springframework.org/schema/tx 
       http://www.springframework.org/schema/tx/spring-tx-4.0.xsd">
       
 <!-- 扫描controller (controller层注入) -->

 <!-- 视图解析器 -->
 <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver" >
    <property name="prefix" value="/WEB-INF/view/"></property>
    <property name="suffix" value=".jsp"></property>
 </bean>
 
 <!-- Enables swgger ui-->
 <mvc:default-servlet-handler/>
 <mvc:resources location="classpath:/META-INF/resources/" mapping="swagger-ui.html"/>
 <mvc:resources location="classpath:/META-INF/resources/webjars/" mapping="/webjars/**"/>
       
</beans>

五.编程demo
接下来给大家写一个简单的新增用户demo（需要其余的demo可以联系我，到时候发给你们）:
1 我用的mysql5.7,先在数据库新建一张表

CREATE DATABASE test;

USE test;

DROP TABLE IF EXISTS `user_t`;

CREATE TABLE `user_t` (
  `user_id` INT(11) NOT NULL AUTO_INCREMENT COMMENT '编号',
  `user_name` VARCHAR(200) DEFAULT NULL COMMENT '姓名',
  `PASSWORD` VARCHAR(200) DEFAULT NULL COMMENT '密码',
   PRIMARY KEY (`user_id`),
   UNIQUE KEY `user_name` (`user_name`)
)COMMENT '测试用户表';

2 现在要写mybatis对应的DaoMapper了：在这里要注意的就是参数对应的jdbcType类型要大写

<?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.zc.dao.user.IUserDao">
<resultMap type="com.zc.model.user.UserVo" id="BaseResultMap">
    <result column="user_id" property="userId" jdbcType="VARCHAR" />
    <result column="user_name" property="userName" jdbcType="VARCHAR" />
    <result column="password" property="password" jdbcType="VARCHAR" />
</resultMap>

<sql id="Base_Column_List">
    user_id, user_name, password
</sql>

<insert id="addUser" parameterType="com.zc.model.user.UserVo">
    insert into user_t
    (
        user_name,
        password
    )
    values
    (
        #{user.userName, jdbcType=VARCHAR},
        #{user.password, jdbcType=VARCHAR}
    )
</insert>
</mapper>

3 接下来写Dao层接口

package com.zc.dao.user;

import java.util.List;

import org.apache.ibatis.annotations.Param;

public interface IUserDao {

/**
 * 新增用户信息
 * @param user
 * @return
 */
int addUser(@Param("user")UserVo user);

}

  1. 创建三个实体类
    1）用户对象实体

     package com.zc.model.user;

 import com.zc.common.BaseVo;

 public class UserVo extends BaseVo {
 private String userId;

 private String userName;

 private String password;


 public String getUserId() {
     return userId;
 }

 public void setUserId(String userId) {
     this.userId = userId;
 }

 public String getUserName() {
     return userName;
 }

 public void setUserName(String userName) {
     this.userName = userName;
 }

 public String getPassword() {
     return password;
 }

 public void setPassword(String password) {
     this.password = password;
 }

 }

2）UserAddRequestDto请求对象实体

package com.zc.facade.dto.request.user;

import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiParam;

@ApiModel(description = "新增用户请求实体")
public class UserAddRequestDto {

private static final long serivalVersionUID = 1L;

@ApiParam(value = "用户名", required = false)
private String userName;

@ApiParam(value = "用户密码", required = false)
private String password;


public String getUserName() {
    return userName;
}

public void setUserName(String userName) {
    this.userName = userName;
}

public String getPassword() {
    return password;
}

public void setPassword(String password) {
    this.password = password;
}

}

3）UserResponseDto请求对象实体

package com.zc.facade.dto.response.user;

import java.util.List;

import javax.xml.bind.annotation.XmlRootElement;

import com.zc.facade.dto.info.UserDto;

public class UserResponseDto {

private static final long serialVersionUID = 1L;

private UserDto user;

public UserDto getUser() {
    return user;
}

public void setUser(UserDto user) {
    this.user = user;
}

}

5 创建一个IUserService接口

package com.zc.service;

import com.zc.facade.dto.request.user.UserAddRequestDto;
import com.zc.facade.dto.response.user.UserResponseDto;

public interface IUserService {

/**
 * 新增用户
 * @param requestDto
 * @return
 * @throws Exception
 */
UserResponseDto addUser(UserAddRequestDto requestDto);

}

6 创建UserServiceImpl实现类

package com.zc.service.impl;

import javax.annotation.Resource;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Service;

import com.zc.common.DataGrid;
import com.zc.dao.user.IUserDao;
import com.zc.facade.dto.request.user.UserAddRequestDto;
import com.zc.facade.dto.response.user.UserResponseDto;
import com.zc.model.user.UserVo;
import com.zc.service.IUserService;

@Service("userService")
public class UserServiceImpl implements IUserService {

private final static Logger logger = LoggerFactory.getLogger(UserServiceImpl.class);

@Resource
private IUserDao userDao;

@Override
public UserResponseDto addUser(UserAddRequestDto requestDto) {
    
    UserResponseDto responseDto = new UserResponseDto();
    
    UserVo user = new UserVo();
    user.setUserName(requestDto.getUserName());
    user.setPassword(requestDto.getPassword());
    
    try {
        int n = userDao.addUser(user);
        if(n==1){
            System.out.println("新增成功");
        }else{
            System.out.println("新增失败");
        }
    } catch (Exception e) {
        System.out.println(e.getMessage());
        logger.error("保存用户信息异常", e);
    }
    
    return responseDto;
}

}

7 创建UserController

package com.zc.web.controller.user;

import javax.annotation.Resource;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;

import com.zc.facade.dto.request.user.UserAddRequestDto;
import com.zc.facade.dto.response.user.UserResponseDto;
import com.zc.service.IUserService;
import com.zc.web.common.ResponseUser;
import com.zc.web.common.RestMessage;

import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import io.swagger.annotations.ApiParam;

@Api(value = "用户服务",description = "提供RESTful风格API的用户的增删改查服务")
@Controller
@RequestMapping("/user")
public class UserController {

private final static Logger logger = LoggerFactory.getLogger(UserController.class);

@Resource
private IUserService userService;

@ApiOperation(value = "新增", notes = "新增用户")
@RequestMapping(value = "/add/userVo", method = RequestMethod.GET)
@ResponseBody
public RestMessage<UserResponseDto> add(UserAddRequestDto requestDto) {
    
    logger.info("add method start,the parameter is :");
    logger.info("requestDto:{},{}", requestDto.getUserName(), requestDto.getPassword());
    
    UserResponseDto responseDto = new UserResponseDto();
    
    responseDto = userService.addUser(requestDto);
    
    return new RestMessage<UserResponseDto>(responseDto);
}

}

8 新增用户demo编写完毕；

9 启动tomcat，因为配置了swagger2,我们用swagger2来测试新增接口：
http://IP:port/{context-path}/swagger-ui.html
例如：http://localhost:8080/test/swagger-ui.html
