整合一个基于java config的spring,mybatis和thymeleaf

工作到现在快要1年半了,一直没有时间自己从头搭建个框架,这个周末实在是无聊,真的不想打lol了,(黑色玫瑰开黑的喊我!),正好把之前埋下的坑填完.
你需要以下工具:
IDE : Intellij idea15
jdk : 1.7.0_59
maven : 3.2.2
tomcat : 7.0.54

new an empty project,相当于eclipse中的workspace

new a maven module,相当于eclipse中的project,选择maven后一路next,设置自己的名称即可.

在idea中配置maven,在preferences中将maven_home指向本地的安装路径即可.至于怎么配置maven_home环境,左转百度,右转google

下面放上一张搭建好的工程结构图

以下是所有使用的到的jar包依赖. (pom.xml)

定义实际使用到的spring mvc config

/**
 * 实际使用到的配置文件
 * 可以将该文件放入不同的工程来辨别使用不同的spring配置,如不同的interceptor
 * Created by sam on 16/5/26.
 */
@EnableWebMvc
@Configuration

public class SpringMvcConfig extends WebMvcConfig {

    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(new SpringInterceptor());
    }
}

以下是上面配置中使用到的interceptor

/**
 * Created by sam on 16/5/26.
 */
@Scope(ConfigurableBeanFactory.SCOPE_PROTOTYPE)
@Component
public class SpringInterceptor extends HandlerInterceptorAdapter {

    private Logger logger = LoggerFactory.getLogger(SpringInterceptor.class);

    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
        logger.debug("interceptor works --------- return true");
        return true;
    }
}

注册DispatcherServlet

/**
 * 注册Spring DispatcherServlet
 * Created by sam on 16/5/26.
 */
public class SpringMvcInitializer extends AbstractAnnotationConfigDispatcherServletInitializer{

    //配置扫描根路径
    @Override
    protected Class<?>[] getRootConfigClasses() {
        return new Class[]{RootConfig.class};
    }

    @Override
    protected Class<?>[] getServletConfigClasses() {
        return new Class<?>[]{};
    }

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

    @Override
    protected Filter[] getServletFilters() {
        CharacterEncodingFilter characterEncodingFilter = new CharacterEncodingFilter();
        characterEncodingFilter.setEncoding("UTF-8");
        characterEncodingFilter.setForceEncoding(true);
        return new Filter[]{characterEncodingFilter};
    }

    @Override
    protected void customizeRegistration(ServletRegistration.Dynamic registration) {
       registration.setInitParameter("throwExceptionIfNoHandlerFound", "true");
    }
}

配置上面配置中的RootConfig,包括配置包的扫描路径,配置mybatis需要的数据源等

/**

 * Created by sam on 16/5/26.
 */
@Configuration
@ComponentScan(basePackages = "com.sam")
@MapperScan(basePackages = "com.sam")
public class RootConfig {

    private static String diver = "com.mysql.jdbc.Driver";

    private static String url = "jdbc:mysql://localhost:3306/YOUR_INSTANCE_NAME";

    private static String user = "YOUR_NAME";

    private static String pwd = "YOUR_PASSWORD";

    @Bean
    public BasicDataSource dataSource() {
        BasicDataSource dataSource = new BasicDataSource();
        dataSource.setDriverClassName(diver);
        dataSource.setUrl(url);
        dataSource.setUsername(user);
        dataSource.setPassword(pwd);
        return dataSource;
    }

    @Bean
    public DataSourceTransactionManager dataSourceTransactionManager() throws NamingException {
        return new DataSourceTransactionManager(dataSource());
    }

    @Bean
    public SqlSessionFactoryBean sqlSessionFactory(ApplicationContext ap) throws Exception {
        SqlSessionFactoryBean sessionFactory = new SqlSessionFactoryBean();
        sessionFactory.setDataSource(dataSource());
        sessionFactory.setTypeAliasesPackage("com.sam");
        return sessionFactory;
    }
}

定义SpringUtils类实现thymeleaf中使用到的自定义参数,这个配置写在WebMvcConfig中

/**
 * 配置thymeleaf自定义参数的相关方法
 * Created by sam on 16/5/26.
 */
public class SpringUtils {

    // 可以在html中使用${e.res('/')}
    // 将会自动代理到相关静态资源下面
    public static String res(String relativeResPath) {
        Minerable resConfig = new Miner().getMiner("poet.base", "res");

        String resVersion = resConfig.getString("version", "1");
        String baseResPath = resConfig.getString("prefix");
        if (baseResPath == null) throw new RuntimeException("prefix config is NULL.");

        return new StringBuilder(removeEnd(baseResPath, "/")).append("/").append(removeStart(relativeResPath, "/")).append("?v=").append(resVersion).toString();
    }
}

定义helloWorldController来测试下

/** 
  * Created by sam on 16/5/26. 
  */
@Controller
@RequestMapping("/hello")
public class HelloWorldController {

    @Autowired
    UserDao userDao;

    private Logger logger = LoggerFactory.getLogger(HelloWorldController.class);

    @RequestMapping("/world")
    public String hello(Model model) {
        String email = "sam@balabala.com";
        String name = userDao.queryUserNameByEmail(email);
        User user = userDao.queryUserInfoByEmail(email);

        logger.debug("you have been here !");
        model.addAttribute("hello", "您好! " + name);
        model.addAttribute("world", "everything is " + user.getUserId());
        return "sam";
    }

    @RequestMapping("/test")
    public String test(Model model){
        logger.debug(">>>>>>>>我就测试下日志 debug  <<<<<<<<<");
        logger.info(">>>>>>>> 我就测试下日志 info   <<<<<<<<<");
        model.addAttribute("hello", "您好! test");
        model.addAttribute("world", "everything is id");
        return "sam";
    }
}

在resources下建views夹子,sam.html如下

<html lang="en">
<head>
    <meta charset="UTF-8"/>
    <title>my first html</title>
</head>
<body>
<h1 data-th-text="${hello}"></h1>
<h1 data-th-text="${world}"></h1>
</body>
</html>

UserDao

/**
 * Created by sam on 16/5/29.
 */
@Service
public interface UserDao {

    @Select("select customer_name from customer where email= #{email}")
    String queryUserNameByEmail(@Param("email") String email);

    User queryUserInfoByEmail(@Param("email") String email);
}

User

/**
 * Created by sam on 16/5/29.
 */
public class User {

    private String userId;

    private String userName;

    private String email;

    //get set toString and so on;
}

在你的MySQL中建一个Customer表(customer_id,customer_name,email)即可
在resources下建立与dao相同包名的xml文件,在你的MySQL中建一个Customer表,包含customer_id,customer_name,email即可,

<?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.sam.dao.UserDao">
    <resultMap id="User" type="com.sam.domain.User">
        <id column="customer_id" property="userId" jdbcType="VARCHAR"/>
        <result column="customer_name" property="userName" jdbcType="VARCHAR"/>
        <result column="email" property="email" jdbcType="VARCHAR"/>
    </resultMap>

    <select id="queryUserInfoByEmail" resultMap="User" parameterType="java.lang.String">
        select customer_id,customer_name,email
        from customer
        where email= #{email,jdbcType=VARCHAR}
    </select>
</mapper>

Finally ,访问 http://localhost:8080/YOUR_MODULE_NAME/hello/world 来试一下吧
