SSM整-整合配置

SSM整合流程

1. 创建工程.
2. SSM整合
   1. Spring
      1. ■SpringConfig
   2. MyBatis
      1. MybatisConfig
      2. JdbcConfig
      3. jdbc. properties
   3. SpringMVC
      1. ServletConfig
      2. SpringMvcConfig
3. 功能模块
   1. 表与实体类
   2. dao (接口+自动代理)
   3. service (接口+实现类)
      1. 业务层接口测试 (整合JUnit )
   4. controller
      1. 表现层接口测试( ApiFox)
          

1、创建工程

2、添加依赖

          <path>/</path>
        </configuration>
      </plugin>
    </plugins>
  </build>

3、SSM整合

创建SpringConfig

@Configuration
@ComponentScan({"com.hyk.service"})
@PropertySource("classpath:jdbc.properties")
@Import({JdbcConfig.class,MyBatisConfig.class})
//开启事务
@EnableTransactionManagement
public class SpringConfig {
}

创建MyBatisConfig

public class MyBatisConfig {
    @Bean
    public SqlSessionFactoryBean sqlSessionFactoryBean(DataSource dataSource){
        SqlSessionFactoryBean sqlSessionFactoryBean = new SqlSessionFactoryBean();
        //设置类型别名的包
        sqlSessionFactoryBean.setTypeAliasesPackage("com.hyk.domain");
        //使用装配注入datasource
        sqlSessionFactoryBean.setDataSource(dataSource);
        return sqlSessionFactoryBean;
    }

    @Bean
    public MapperScannerConfigurer mapperScannerConfigurer(){
        MapperScannerConfigurer msc = new MapperScannerConfigurer();
        //设置映射的包
        msc.setBasePackage("com.hyk.dao");
        return msc;
    }
}

创建JdbcConfig

public class JdbcConfig {
    @Value("${jdbc.driver}")
    private String driver;
    @Value("${jdbc.url}")
    private String url;
    @Value("${jdbc.username}")
    private String username;
    @Value("${jdbc.password}")
    private String password;

    @Bean
    public DataSource dataSource(){
        DruidDataSource dataSource = new DruidDataSource();
        dataSource.setDriverClassName(driver);
        dataSource.setUrl(url);
        dataSource.setUsername(username);
        dataSource.setPassword(password);
        return  dataSource;
    }
    @Bean
    public PlatformTransactionManager transactionManager(DataSource dataSource){
        DataSourceTransactionManager ds = new DataSourceTransactionManager();
        ds.setDataSource(dataSource);
        return ds;
    }

}

创建jdbc.porperties

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/restaruant?characterEncoding=utf8&serverTimezone=Asia/Shanghai
jdbc.username=root
jdbc.password=123456

创建SpringMvcConfig

@Configuration
@ComponentScan("com.hyk.controller")
@EnableWebMvc
public class SpringMvcConfig {
}

创建ServletConfig

public class ServletConfig extends AbstractAnnotationConfigDispatcherServletInitializer {
    @Override
    protected Class<?>[] getRootConfigClasses() {
        return new Class[]{SpringConfig.class};
    }

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

    @Override
    protected String[] getServletMappings() {
        return new String[]{"/"};
    }
    //乱码处理
    @Override
    protected Filter[] getServletFilters() {
        CharacterEncodingFilter filter = new CharacterEncodingFilter();
        filter.setEncoding("UTF-8");
        return new Filter[]{filter};
    }
}
