spring+springmvc+mybatis基于注解最简洁的配置

在ecplise新建maven工程 file->new->maven

这里选择最后一个

maven新建完成之后开始配置pom.xml

其中pom.xml的配置文件如下

web.xml文件的配置如下：

<web-app>
    <display-name>电影</display-name>
    <servlet>
        <servlet-name>spring</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet

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


</web-app>

spring-servlet.xml文件配置如下

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

</beans>  

其中 <context:component-scan base-package="com.bluethink.movie.controller"></context:component-scan>表示spring自动扫描的包

mybatis的配置文件：

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

    </bean>
    <!-- 事务注解驱动，标注@Transactional的类和方法将具有事务性 -->
    <tx:annotation-driven transaction-manager="transactionManager"/>
</beans>

其中     <property name="url" value="jdbc:mysql://localhost:3308/movie"></property>
        <property name="username" value="root"></property>
        <property name="password" value="*****"></property>代表本地的数据库名称和密码

log4j的配置文件：

log4j.rootLogger=DEBUG,Console,File


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=[%c]%m%n


log4j.appender.File=org.apache.log4j.RollingFileAppender
log4j.appender.File.File=D\:/logs/usercenter.log
log4j.appender.File.MaxFileSize=10MB
log4j.appender.File.Threshold=ALL
log4j.appender.File.layout=org.apache.log4j.PatternLayout
log4j.appender.File.layout.ConversionPattern=[%p][%d{yyyy-MM-dd HH\:mm\:ss,SSS}][%c]%m%n

fastjson的配置文件：

<?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:mvc="http://www.springframework.org/schema/mvc"

            <bean class="org.springframework.http.converter.StringHttpMessageConverter">
                <constructor-arg value="UTF-8"/>
            </bean>
            <!-- 配置Fastjson支持 -->
            <bean class="com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter">
                <property name="supportedMediaTypes">
                    <list>

                </property>
            </bean>
        </mvc:message-converters>
    </mvc:annotation-driven>
</beans>

以上配置完成之后的目录如图所示

在src/main/java中新建文件夹如图所示

在src/main/resource中写xml文件，如下所示：

<?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.bluethink.movie.mapping.moviemapper">
<resultMap id="BaseResultMap" type="com.bluethink.movie.model.movie">
<result column="movie_id" property="movieId" jdbcType="SMALLINT" />
<result column="movie_name" property="movieName" jdbcType="VARCHAR" />
<result column="movie_privace" property="moviePrivace" jdbcType="SMALLINT" />
</resultMap>

<select id="selectMovie" resultMap="BaseResultMap">
select * from movie
</select>
</mapper>

column对应数据库的字段， property对应模型里面的字段 namespace对应映射文件的路径  

moviemapper中的写法：

import java.util.List;
import com.bluethink.movie.model.movie;
public interface moviemapper {

/**
* 
* @return
*/
List<movie> selectMovie();
}

dao里面的例子：

@Repository
@Service("movieDaoService")
public class movieDaoImpl {
@Autowired
private moviemapper movieMapper;
public List<movie> findAll() {
return movieMapper.selectMovie();
}
}

controller里面的例子：

import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.CrossOrigin;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import com.bluethink.movie.dao.movieDaoImpl;
import com.bluethink.movie.model.movie;
@CrossOrigin(origins = "*", maxAge = 3600)
@RestController
@RequestMapping(value = "/movie/")
public class movieController {
  @Autowired
  movieDaoImpl movieDaoService;
@RequestMapping(value="/findAll")
  public List<movie> findAll(){
  return movieDaoService.findAll();
  }
}

最后的文件目录如图所示：
