将Spring Session JDBC与现有数据库一起使用(而非springboot)

我的应用程序在没有Spring Boot的情况下与Spring Web MVC框架一起运行。现在,我想使用spring session JDBC将会话存储到应用程序使用的数据库中。我在网上找到的所有示例都使用spring boot,如果不使用spring boot,则它们使用的数据源配置为EmbeddedDatabase,如下所示:

    @Bean
    public EmbeddedDatabase dataSource() {
            return new EmbeddedDatabaseBuilder() 
                            .setType(EmbeddedDatabaseType.H2)
                            .addScript("org/springframework/session/jdbc/schema-h2.sql").build();
    }

我具有使用HikariCP的数据源配置,并且我希望Spring会话使用此数据源配置。

@Bean
public DataSource dataSource() {
    HikariConfig config = new HikariConfig();
    config.setDriverClassName(env.getRequiredProperty("jdbc.driver"));
    config.setJdbcUrl(env.getRequiredProperty("jdbc.url"));
    config.setUsername(env.getRequiredProperty("jdbc.username"));
    config.setPassword(env.getRequiredProperty("jdbc.password"));
    config.setMinimumIdle(env.getRequiredProperty("jdbc.pool.minimumIdle", Integer.class));
    config.setMaximumPoolSize(env.getRequiredProperty("jdbc.pool.maximumPoolSize", Integer.class));
    config.addDataSourceProperty("cachePrepStmts", env.getRequiredProperty("jdbc.prop.cachePrepStmts"));
    config.addDataSourceProperty("prepStmtCacheSize", env.getRequiredProperty("jdbc.prop.prepStmtCacheSize"));
    config.addDataSourceProperty("prepStmtCacheSqlLimit", env.getRequiredProperty("jdbc.prop.prepStmtCacheSqlLimit"));
    HikariDataSource ds = new HikariDataSource(config);
    return ds;
}

如何使用当前配置与spring session集成?

@Autowired
    private Environment env;

@Bean
    public PlatformTransactionManager transactionManager () {

        EntityManagerFactory factory = entityManagerFactory();
        return new JpaTransactionManager(factory);
    }


@Bean
    public EntityManagerFactory entityManagerFactory () {
        HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
        vendorAdapter.setShowSql(Boolean.TRUE);
        LocalContainerEntityManagerFactoryBean factory = new LocalContainerEntityManagerFactoryBean();
        factory.setJpaVendorAdapter(vendorAdapter);
        factory.setPackagesToScan("com.your.domain.project");
        factory.setDataSource(dataSource());
        factory.setJpaProperties(additionalProperties()); // any addtional properties of your ORM
        factory.afterPropertiesSet();
        factory.setLoadTimeWeaver(new InstrumentationLoadTimeWeaver());
        return factory.getObject();
    }


@Bean
    public DataSource dataSource () {

        final com.mchange.v2.c3p0.ComboPooledDataSource comboDataSource = new ComboPooledDataSource();

        try {
            comboDataSource.setDriverClass(env.getProperty("jdbc.driver"));
            comboDataSource.setJdbcUrl(env.getProperty("jdbc.url"));
            comboDataSource.setUser(env.getProperty("jdbc.user"));
            comboDataSource.setPassword(env.getProperty("jdbc.properties"));

        } catch (PropertyVetoException e) {
            e.printStackTrace();
        }
        return comboDataSource;
    }


这肯定会对您有所帮助。

据我了解,spring-session javaconfig-jdbc sample / doc,您“只是”需要:

  1. YourConfig注释“您的配置类”(org.springframework.session.jdbc.config.annotation.web.http.EnableJdbcHttpSession)。

  2. 名称您的DataSource“数据源”。 (完成!;)

  3. 基于PlatformTransactionManager中的dataSource提供一个YourConfig bean。

  4. (在servlet环境中-如您所愿)引入引用AbstractHttpSessionApplicationInitializer的{​​{1}}(在类路径中):

    YourConfig

如果您希望手动安装数据库模式或使用外部工具,SQL脚本位于spring-session.jar中。 (!org / springframework / session / jdbc / schema-@@ platform @@。sql)文件或分别为in the source code repository


这些(应用程序)属性允许进一步自定义:

public class Initializer extends org.springframework.session.web.context.AbstractHttpSessionApplicationInitializer { // <1>

  public Initializer() {
    super(YourConfig.class); // <2>
  }
}

  • 在jar /源代码分发中,您还将找到“清理”(-drop)脚本
  • ,当前提供的平台是:

    # Session store type. [jdbc|redis|hazelcast|mongodb]
    spring.session.store-type=jdbc
    # Session timeout. If a duration suffix is not specified, seconds will be used.
    server.servlet.session.timeout= 
    # Database schema initialization mode. [alwys | never | embedded]
    spring.session.jdbc.initialize-schema=always 
    # Path to the SQL file to use to initialize the database schema.(see: https://github.com/spring-projects/spring-session/tree/master/spring-session-jdbc/src/main/resources/org/springframework/session/jdbc)
    spring.session.jdbc.schema=classpath:org/springframework/session/jdbc/schema-@@platform@@.sql
    # custom spring session table name (see : https://github.com/spring-projects/spring-session/issues/1230) 
    spring.session.jdbc.table-name=SPRING_SESSION
