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:
用YourConfig
注释“您的配置类”(org.springframework.session.jdbc.config.annotation.web.http.EnableJdbcHttpSession
)。
名称您的DataSource
“数据源”。 (完成!;)
基于PlatformTransactionManager
中的dataSource
提供一个YourConfig
bean。
(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>
}
}
,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
