[非SpringBoot方式]Spring 5.2.6 集成 Spring session jdbc 2.3.0

spring session的官方文檔對SpringBoot方式和xml配置方式介紹的都比較詳細，大家應該都能看懂。但java 類配置的方式個人覺得不是很詳細, 有的地方可能讓人走彎路. 另外若不配springSessionRepositoryFilter會無法寫入,但這個類在哪找了一會沒有發現其真身.

第一步: pom.xml需要的依賴:

        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-web</artifactId>
            <version>${spring-framework.version}</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.session</groupId>
            <artifactId>spring-session-core</artifactId>
            <version>2.3.0.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.session</groupId>
            <artifactId>spring-session-jdbc</artifactId>
            <version>2.3.0.RELEASE</version>
        </dependency>

第二步: Spring session的配置文件：

/**
 * Spring session的配置文件
 * @author xiaofanku
 * @since 20200602
 */
@Configuration
@EnableJdbcHttpSession
public class SpringSessionConfig{
    @Bean
    public SpringHttpSessionConfiguration init(){
        JdbcHttpSessionConfiguration config = new org.springframework.session.jdbc.config.annotation.web.http.JdbcHttpSessionConfiguration();
        config.setTableName("spring_session");
        return config;
    }
}

XML配置的方式官方文檔介紹的非常詳細: Spring XML Configuration

第三步: 將SpringSessionConfig導入到Spring Application的配置文件中

/**
 * Spring framework配置類
 *
 * @author xiaofanku
 * @since 20200511
 */
@Configuration
@PropertySource("classpath:global.properties")
@EnableLoadTimeWeaving
@EnableAspectJAutoProxy(proxyTargetClass=true)
@EnableTransactionManagement(proxyTargetClass = true)
@Import(value = {SpringSessionConfig.class})
public class ThronesAppConfig {
    @Autowired
    private Environment env;
}

因爲在SpringSessionConfig類中沒有配置數據源(DataSource)和事務管理器(PlatformTransactionManager )，這個類配置文件中需要有相應的@Bean註解的方法, 不一定非要是返回值PlatformTransactionManager的方法,它的實現類也可以,我在這個類中用的是JpaTransactionManager

第四步: 攔截器springSessionRepositoryFilter

/**
 * Spring 項目啓動類
 *
 * @author xiaofanku
 * @since 20200511
 */
public class App extends AbstractAnnotationConfigDispatcherServletInitializer {
    //ETC
    @Override
    protected Filter[] getServletFilters() {
        DelegatingFilterProxy filterProxy = new DelegatingFilterProxy();
        filterProxy.setTargetBeanName("springSessionRepositoryFilter");
        return new Filter[]{
            new org.springframework.web.filter.CharacterEncodingFilter("UTF-8", true), 
            filterProxy};
    }
}

最後: 成功了
