2 純註解配置方式
2.1 Spring整合MyBatis
MyBatis對映 - UserDao
public interface UserDao {
@Insert("insert into user(userName,password)values(#{userName},#{password})")
public boolean save(User user);
@Update("update user set userName=#{userName},password=#{password} where uuid=#{uuid}")
public boolean update(User user);
@Delete("delete from user where uuid = #{uuid}")
public boolean delete(Integer uuid);
@Select("select * from user where uuid = #{uuid}")
public User get(Integer uuid);
@Select("select * from user")
public List<User> getAll();
@Select("select * from user where userName=#{userName} and password=#{password}")
public User getByUserNameAndPassword(@Param("userName") String userName,
@Param("password") String password);
}
配置類 config包 - JdbcConfig類
public class JdbcConfig {
//使用注入的形式,讀取properties檔案中的屬性值,等同於<property name="*******" value="${jdbc.driver}"/>
@Value("${jdbc.driver}")
private String driver;
@Value("${jdbc.url}")
private String url;
@Value("${jdbc.username}")
private String userName;
@Value("${jdbc.password}")
private String password;
//定義dataSource的bean,等同於<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">
@Bean("dataSource")
public DataSource getDataSource(){
//建立物件
DruidDataSource ds = new DruidDataSource();
//手工呼叫set方法,等同於set屬性注入<property name="driverClassName" value="******"/>
ds.setDriverClassName(driver);
ds.setUrl(url);
ds.setUsername(userName);
ds.setPassword(password);
return ds;
}
}
配置類 config包 - MyBatisConfig類
public class MyBatisConfig {
//定義MyBatis的核心連線工廠bean,等同於<bean class="org.mybatis.spring.SqlSessionFactoryBean">
@Bean
//引數使用自動裝配的形式載入dataSource,為set注入提供資料,dataSource來源於JdbcConfig中的配置
public SqlSessionFactoryBean getSqlSessionFactoryBean(@Autowired DataSource dataSource,@Autowired Interceptor interceptor){
SqlSessionFactoryBean ssfb = new SqlSessionFactoryBean();
//等同於<property name="typeAliasesPackage" value="com.itheima.domain"/>
ssfb.setTypeAliasesPackage("com.itheima.domain");
//等同於<property name="dataSource" ref="dataSource"/>
ssfb.setDataSource(dataSource);
// //等同於<bean class="com.github.pagehelper.PageInterceptor">

ssfb.setPlugins(interceptor);
return ssfb;
}
//定義MyBatis的對映掃描,等同於<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
@Bean
public MapperScannerConfigurer getMapperScannerConfigurer(){
MapperScannerConfigurer msc = new MapperScannerConfigurer();
//等同於<property name="basePackage" value="com.itheima.dao"/>

Properties properties = new Properties();
properties.setProperty("helperDialect","mysql");
properties.setProperty("reasonable","true");
//等同於<property name="properties">
interceptor.setProperties(properties);
return interceptor;
}
}
配置類 config包 - SpringConfig類
import javax.sql.DataSource;
@Configuration
//等同於<context:component-scan base-package="com.itheima">
@ComponentScan(value = "com.itheima",excludeFilters =
//等同於<context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
@ComponentScan.Filter(type= FilterType.ANNOTATION,classes = {Controller.class}))
//等同於<context:property-placeholder location="classpath*:jdbc.properties"/>
@PropertySource("classpath:jdbc.properties")
//等同於<tx:annotation-driven />,bean的名稱預設取transactionManager
@EnableTransactionManagement
@Import({MyBatisConfig.class,JdbcConfig.class})
public class SpringConfig {
//等同於<bean id="txManager"/>
@Bean("transactionManager")
//等同於<bean class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
public DataSourceTransactionManager getTxManager(@Autowired DataSource dataSource){
DataSourceTransactionManager tm = new DataSourceTransactionManager();
//等同於<property name="dataSource" ref="dataSource"/>
tm.setDataSource(dataSource);
return tm;
}
}
2.2 Spring整合SpringMVC
配置類 config包 - ServletContainersInitConfig類
public class ServletContainersInitConfig extends AbstractDispatcherServletInitializer {
//建立Servlet容器時,使用註解的方式載入SPRINGMVC配置類中的資訊,並載入成WEB專用的ApplicationContext物件
//該物件放入了ServletContext範圍,後期在整個WEB容器中可以隨時獲取呼叫
@Override
protected WebApplicationContext createServletApplicationContext() {
AnnotationConfigWebApplicationContext ctx = new AnnotationConfigWebApplicationContext();
ctx.register(SpringMvcConfig.class);
return ctx;
}
//註解配置對映地址方式,服務於SpringMVC的核心控制器DispatcherServlet
@Override
protected String[] getServletMappings() {
return new String[]{"/"};
}
@Override
//基本等同於<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
protected WebApplicationContext createRootApplicationContext() {
AnnotationConfigWebApplicationContext ctx = new AnnotationConfigWebApplicationContext();
ctx.register(SpringConfig.class);
return ctx;
}
//亂碼處理作為過濾器,在servlet容器啟動時進行配置,相關內容參看Servlet零配置相關課程
@Override
public void onStartup(ServletContext servletContext) throws ServletException {
//觸發父類的onStartup
super.onStartup(servletContext);
//1.建立字符集過濾器物件
CharacterEncodingFilter cef = new CharacterEncodingFilter();
//2.設定使用的字符集
cef.setEncoding("UTF-8");
//3.新增到容器(它不是ioc容器,而是ServletContainer)
FilterRegistration.Dynamic registration = servletContext.addFilter("characterEncodingFilter", cef);
//4.新增對映
registration.addMappingForUrlPatterns(EnumSet.of(DispatcherType.REQUEST, DispatcherType.FORWARD, DispatcherType.INCLUDE), false, "/*");
}
}
配置類 config包 - SpringMvcConfig類
@Configuration
//等同於<context:component-scan base-package="com.itheima.controller"/>
@ComponentScan("com.itheima.controller")
//等同於<mvc:annotation-driven/>,還不完全相同
@EnableWebMvc
public class SpringMvcConfig {
}
