spring、springmvc和mybatis整合（java config方式）

　　之前项目中使用ssm框架大多是基于xml的方式，spring3.0以后就提供java config的模式来构建项目，并且也推荐使用这种方式，自从接触过springboot后，深深感受到这种纯java配置的便利，但是springboot默认为我们引入好多jar和配置，使得项目变得很重，因此决定自己动手搭建一个无xml的ssm项目。

　　开发环境

　　我的开发环境如下：

　　web服务器：tomcat8

　　开发工具：STS

　　JDK版本：1.8

　　项目构建工具：maven

　　搭建过程

　　1、首先引入相关依赖

　　pom文件如下：

　2、编写配置文件

　　MyWebAppInitializer继承AbstractAnnotationConfigDispatcherServletInitializer，并重写其中的方法（另外一种方式是MyWebAppInitializer直接实现WebApplicationInitializer接口，不过会复杂一点），它是我们程序的入口，web容器启动后会调其中相关的方法从而启动整个应用。主要实现3个方法：getRootConfigClasses，负责加载spring容器，本例中我们只加载了RootConfig类，其它一些spring相关配置类也可以在这里加载；getServletConfigClasses，加载springmvc容器，本例中我们加载了MvcConfig；getServletMappings，设置映射的路径。配置代码如下：

　　MyWebAppInitializer.java

package powerx.io.config;

import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;

public class MyWebAppInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {

    protected Class<?>[] getRootConfigClasses() {
        return new Class<?>[]{RootConfig.class};
    }

    protected Class<?>[] getServletConfigClasses() {
        return new Class<?>[]{MvcConfig.class};
    }

    protected String[] getServletMappings() {
        return new String[]{"/"};
    }
}

　　RootConfig.java

package powerx.io.config;

import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.FilterType;
import org.springframework.context.annotation.Import;
import org.springframework.transaction.annotation.EnableTransactionManagement;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;

@Configuration
@EnableTransactionManagement //开启事务支持
@Import(DruidDataSourceConfig.class)//导入数据源的配置
@ComponentScan(basePackages = {"powerx.io.service","powerx.io.dao","powerx.io.config"},
    excludeFilters = {@ComponentScan.Filter(type = FilterType.ANNOTATION, value = EnableWebMvc.class)})
public class RootConfig {
}

　　MvcConfig.java

package powerx.io.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.ViewResolver;
import org.springframework.web.servlet.config.annotation.DefaultServletHandlerConfigurer;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.ViewControllerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
import org.springframework.web.servlet.view.InternalResourceViewResolver;

@Configuration
@EnableWebMvc
@ComponentScan("powerx.io.controller")
public class MvcConfig extends WebMvcConfigurerAdapter{

    @Override
    public void addViewControllers(ViewControllerRegistry registry) {
        registry.addViewController("/").setViewName("index");
        super.addViewControllers(registry);
    }

    //配置jsp视图
    @Bean
    public ViewResolver viewResolver(){
        InternalResourceViewResolver resolver = new InternalResourceViewResolver();
        resolver.setPrefix("/WEB-INF/");
        resolver.setSuffix(".jsp");
        resolver.setExposeContextBeansAsAttributes(true);
        return resolver;
    }

    //配置静态资源处理
    @Override
    public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
        configurer.enable();//将静态资源的请求转发到servlet容器中默认的servlet上
    }
}

　　DruidDataSourceConfig.java

package powerx.io.config;

import java.io.IOException;
import java.sql.SQLException;

import javax.sql.DataSource;

    @Bean     //声明其为Bean实例
    public DataSource dataSource(){
        DruidDataSource datasource = new DruidDataSource();  

        datasource.setUrl(this.dbUrl);
        datasource.setUsername(username);
        datasource.setPassword(password);
        datasource.setDriverClassName(driverClassName);

        SqlSessionFactoryBean sqlSessionFactoryBean = new SqlSessionFactoryBean();//mybatis-plus插件类
        sqlSessionFactoryBean.setDataSource(dataSource());//数据源
        sqlSessionFactoryBean.setMapperLocations(resourcePatternResolver.getResources("classpath:mappers/*.xml"));
        sqlSessionFactoryBean.setTypeAliasesPackage("powerx.io.model");//别名，让*Mpper.xml实体类映射可以不加上具体包名
        return sqlSessionFactoryBean;
    }
}

　　3、配置数据源和mapper映射文件等

　　jdbc.properties

spring.datasource.type=com.alibaba.druid.pool.DruidDataSource
spring.datasource.driverClassName=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/testssm
spring.datasource.username=root
spring.datasource.password=root
spring.datasource.initialSize=5
spring.datasource.minIdle=5
spring.datasource.maxActive=20
spring.datasource.maxWait=60000
spring.datasource.timeBetweenEvictionRunsMillis=60000
spring.datasource.minEvictableIdleTimeMillis=300000
spring.datasource.validationQuery=SELECT 1 FROM DUAL
spring.datasource.testWhileIdle=true
spring.datasource.testOnBorrow=false
spring.datasource.testOnReturn=false
spring.datasource.poolPreparedStatements=true
spring.datasource.maxPoolPreparedStatementPerConnectionSize=20
spring.datasource.filters=stat
spring.datasource.connectionProperties=druid.stat.mergeSql=true;druid.stat.slowSqlMillis=5000

　　UserMapper.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="powerx.io.dao.UserDao">
    <resultMap type="User" id="UserResult">
        <!-- 数据库字段和实体类属性映射关系，名称一样的字段可以无需映射。column对应数据库的实际字段，property对应实体类的属性 -->
        <result column="USER_NAME" property="userName" />
        <result column="USER_PWD" property="userPwd" />
    </resultMap>

    <select id="findByName" parameterType="String" resultMap="UserResult">
        SELECT USER_NAME,USER_PWD FROM USER WHERE USER_NAME=#{userName}
    </select>

    <insert id="insertUser" parameterType="powerx.io.model.User">
    INSERT INTO USER(USER_NAME,USER_PWD) VALUES(#{userName},#{userPwd})
  </insert>

</mapper>

　　User.java

package powerx.io.model;

public class User {

    private String userName;
    private String userPwd;
    public String getUserName() {
        return userName;
    }
    public void setUserName(String userName) {
        this.userName = userName;
    }
    public String getUserPwd() {
        return userPwd;
    }
    public void setUserPwd(String userPwd) {
        this.userPwd = userPwd;
    }

}

　　UserDao.java　

package powerx.io.dao;

import powerx.io.model.User;

public interface UserDao {

    User findByName(String userName);

    int insertUser(User user);
}

4、控制层和service层

　　UserService.java

package powerx.io.service;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import powerx.io.dao.UserDao;
import powerx.io.model.User;

@Service
public class UserService {

    @Autowired
    private UserDao userDao;
    public Object findByName(String userName) {
        return userDao.findByName(userName);
     }

    @Transactional
    public int insertUser(User user) {
        //测试事务是否起作用
        userDao.insertUser(user);
        return userDao.insertUser(user);
     }

}

　　UserContoller.java

package powerx.io.controller;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

import powerx.io.model.User;
import powerx.io.service.UserService;

@Controller
public class UserContoller {

    public static Logger logger = LoggerFactory.getLogger("monitor");
    @Autowired
    private UserService userService;

    @ResponseBody
    @RequestMapping("/get")
    public Object getData(String userName) {
        logger.info("获取用户信息");
        return userService.findByName(userName);
    }

    @ResponseBody
    @RequestMapping("/insert")
    public Object insert(User user) {
        logger.info("添加用户");
        return userService.insertUser(user);
    }
}

5、项目结构图

　　

　　总结

　　写完代码，在往tomcat中部署运行的时候遇到了一个问题，tomcat启动失败，报了一大堆异常，其中一个是java.util.zip.ZipException: invalid LOC header (bad signature)，从网上找了一大堆答案，基本肯定是依赖的jar包不完整造成的，但是我搜索了一下maven仓库，删除了所有in_progress的包，依然不行，无奈只能一个一个的排除，浪费了好久时间，最后查出原因是因为mysql的包没有下载完整，但是依然是一个.jar结尾的文件，只不过大小不对，所以在此记录一下，以后在遇到tomcat启动失败问题，一定要细心排查所依赖的jar。

　　至此，整个ssm框架搭建完毕，在其中我加入了事务控制和日志管理，基本上可以作为一个生产项目的基础demo。项目代码基本上都以贴上，我也上传到了码云上面，方便自己使用，地址：https://gitee.com/hehang_com/ssm.git。
