我面临一个使用Hibernate 5.1.5.Final实现多租户实现的问题。
我已提出MultiTenantConnectionProvider和CurrentTenantIdentifierResolver。以下是他们的意见。
public class TenantIdentifierAndSchemaResolver implements CurrentTenantIdentifierResolver {
private String tenantIdentifier;
@Override
public String resolveCurrentTenantIdentifier() {
return this.tenantIdentifier;
}
@Override
public boolean validateExistingCurrentSessions() {
return false;
}
public void setTenantIdentifier(String tenantIdentifier) {
this.tenantIdentifier = tenantIdentifier;
}
}
并且
public class CustomMultiTenantConnectionProvider implements MultiTenantConnectionProvider {
private BasicDataSource dataSource;
public void setDataSource(BasicDataSource dataSource) {
this.dataSource = dataSource;
}
@Override
public Connection getAnyConnection() throws SQLException {
if (LOG.isDebugEnabled()) {
LOG.debug("Fetching any connection >");
}
return dataSource.getConnection();
}
@Override
public Connection getConnection(String tenantIdentifier) throws SQLException {
Connection tenantSpecificConnection = dataSource.getConnection();
if (!StringUtils.isEmpty(tenantIdentifier)) {
Statement statement = tenantSpecificConnection.createStatement();
statement.executeQuery("use " + tenantIdentifier);
statement.close();
tenantSpecificConnection.setSchema(tenantIdentifier);
} else {
tenantSpecificConnection.setSchema(Constants.ELMEX);
}
return tenantSpecificConnection;
}
@Override
public void releaseAnyConnection(Connection connection) throws SQLException {
if (LOG.isDebugEnabled()) {
LOG.debug("Releasing connection obtained by : getAnyConnection", connection);
}
connection.close();
}
@Override
public void releaseConnection(String tenantIdentifier, Connection connection) throws SQLException {
if (LOG.isDebugEnabled()) {
LOG.debug("Releasing connection for : {}", tenantIdentifier);
}
}
@Override
public boolean supportsAggressiveRelease() {
return false;
}
@SuppressWarnings("rawtypes")
@Override
public boolean isUnwrappableAs(Class arg0) {
return false;
}
@Override
public <T> T unwrap(Class<T> arg0) {
return null;
}
}
我收到以下错误。

我尝试调试它，发现TenantIdentifierAndSchemaResolver的方法setTenantIdentifier和resolveCurrentTenantIdentifier被调用，但两者都在不同的对象上调用，因此我以前设置的tenantIdentifier是在第二个对象中找到null。
我还有一个过滤器，它根据网址中的子域确定租户。我已经自动装配了TenantIdentifierAndSchemaResolver对象，如下所示
if (tenantIdentifierAndSchemaResolver == null) {
// SpringBeanAutowiringSupport.processInjectionBasedOnCurrentContext(this);
tenantIdentifierAndSchemaResolver = (TenantIdentifierAndSchemaResolver) WebApplicationContextUtils
.getRequiredWebApplicationContext(request.getServletContext())
.getBean("multitenantSchemaResolverAndTenantIdentifier");
}
如果您需要任何其他配置/代码，请告诉我。
