修复注销错误 "No database selected" 尝试在 Hibernate Spring 引导中使用基于会话的身份验证实现多租户服务时
Fix Logout error "No database selected" when trying to implement multi tenancy services in Hibernate Spring boot using session based auth
我正在使用 Hibernate Spring 引导将多租户逻辑集成到我的项目中，我能够使用 DNS 方法在数据库之间进行交换，
例如：
db_name.example.com -> 数据库名称 = db_name
我在项目中使用基于会话的身份验证。
问题是当我想注销会话时，项目return出现以下错误：
[从 persistent_logins 中删除用户名 = ?]； SQL状态[3D000]；错误代码 [1046]；没有选择数据库;嵌套异常是 java.sql.SQLException：未选择数据库
我发现这个 post 与我的情况相似，
我已经试过了，但是没有用。
我正在使用从以下网站获取的以下多租户代码示例
https://javadeveloperzone.com/hibernate/spring-hibernate-xml-multi-tenancy-example/ (tocker评论是我)
我的安全配置网站：
public class SecurityConfigWeb extends WebSecurityConfigurerAdapter implements Serializable {
@Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests()

谁能帮我们解决问题或提出解决方案？..
提前致谢！
已实现，解决方法如下：
创建JdbcTokenExtend class 在 JdbcTokenRepositoryImpl 上复制：
package com.lbc.takeoff.neorcha.web;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.util.Date;
import javax.servlet.http.HttpServletRequest;

import org.springframework.web.context.request.ServletRequestAttributes;
public class JdbcTokenExtend extends JdbcDaoSupport implements PersistentTokenRepository{
private boolean createTableOnStartup;

if (createTableOnStartup) {
getJdbcTemplate().execute("create table " + getSchemaName() + ".persistent_logins (username varchar(64) not null, series varchar(64) primary key, "
+ "token varchar(64) not null, last_used timestamp not null)");
}
}
public void createNewToken(PersistentRememberMeToken token) {

token.getTokenValue(), token.getDate());
}
public void updateToken(String series, String tokenValue, Date lastUsed) {
getJdbcTemplate().update("update " + getSchemaName() + ".persistent_logins set token = ?, last_used = ? where series = ?", tokenValue, lastUsed, series);
}
/**

*/
public PersistentRememberMeToken getTokenForSeries(String seriesId) {
try {
return getJdbcTemplate().queryForObject("select username,series,token,last_used from " + getSchemaName() + ".persistent_logins where series = ?",
new RowMapper<PersistentRememberMeToken>() {
public PersistentRememberMeToken mapRow(ResultSet rs, int rowNum)
throws SQLException {
return new PersistentRememberMeToken(rs.getString(1), rs
.getString(2), rs.getString(3), rs.getTimestamp(4));
}
}, seriesId);
}
catch (EmptyResultDataAccessException zeroResults) {
if (logger.isDebugEnabled()) {
logger.debug("Querying token for series '" + seriesId
+ "' returned no results.", zeroResults);
}
}
catch (IncorrectResultSizeDataAccessException moreThanOne) {

}
catch (DataAccessException e) {
logger.error("Failed to load token for series " + seriesId, e);
}
return null;
}
public void removeUserTokens(String username) {
getJdbcTemplate().update("delete from " + getSchemaName() + ".persistent_logins where username = ?", username);
}
/**
* Intended for convenience in debugging. Will create the persistent_tokens database
* table when the class is initialized during the initDao method.

*/
public void setCreateTableOnStartup(boolean createTableOnStartup) {
this.createTableOnStartup = createTableOnStartup;
}
public String getSchemaName() {
// taking the schema name from the schema_name.dns.com
final ServletRequestAttributes attr = (ServletRequestAttributes) RequestContextHolder.currentRequestAttributes();
final HttpServletRequest request = attr.getRequest();
String requestUrl = request.getRequestURL().toString();
String schemaName = requestUrl.substring(requestUrl.lastIndexOf("://") + 3, requestUrl.lastIndexOf(".dns.com"));
return schemaName;
}
}
在 SecurityConfigWeb 中：
/**
* This bean is the JDBC token repository for remember me services.
*/
@Bean
public PersistentTokenRepository persistentTokenRepository() {
// JdbcTokenRepositoryImpldb = new JdbcTokenRepositoryImpl(); // old code deleted
JdbcTokenExtend db = new JdbcTokenExtend(); // created this java class (copy on JdbcTokenRepositoryImpl)
db.setCreateTableOnStartup(false);
db.setDataSource(dataSource);
return db;
}
此更改已解决问题，因为现在 "delete from persistent_logins where username" 已分配给特定的架构名称
我正在使用 Hibernate Spring 引导将多租户逻辑集成到我的项目中，我能够使用 DNS 方法在数据库之间进行交换， 例如： db_name.example.com -> 数据库名称 = db_name 我在项目中使用基于会话的身份验证。
