Connection is read-only.

写一个批量删除的代码,结果报连接只读,操作不被允许。。。从网上查过类似问题的都无法解决。
这是事务配置:
tx:attributes




/tx:attributes
没有配置read-only,应该不是这个问题吧。

还有就是其中有两个地方用到批量删除的,其中有一个就能够正常删除。第二个代码一样,只是操作的数据表不一样,就是无法操作成功。求大神解救

操作的数据表有没有可能被锁着,,,

springboot 连接mycat 报 Connection is read-only

使用springboot连接mycat(底层是oracle), 查询数据正常,在写入数据的时候报 Caused by: java.sql.SQLException: Connection is read-only. Queries leading to data modification are not allowed 请各位大侠帮忙看看,是否在配置文件中要加点什么,事务配置有尝试过,没有什么用。用mysql客户端操作同一个用户,是可以正常读写,配置文件如下: spring: http: multipart: enabled: true max-file-size: 3000MB max-request-size: 900000MB datasource: read-only: false url: jdbc:mysql://172.18.58.188:8066/abmdb11 username: test password: ENC(7BjKLN7o22PyA0JTSu/KhA==) driver-class-name: com.mysql.jdbc.Driver type: org.apache.tomcat.jdbc.pool.DataSource tomcat: validation-query: select * from dual jpa: show-sql: true database-platform: org.hibernate.dialect.MySQL5Dialect hibernate: ddl-auto: none

MySQL存储过程的问题

存储过程 [code="sql"] BEGIN declare iLockedDrawed int; declare iOutmanDrawed int; SELECT `lockedDrawed` INTO iLockedDrawed FROM `qb_award` WHERE `id`=awardId; SET iLockedDrawed = iLockedDrawed + 1; UPDATE `qb_award` SET `lockedDrawed`=iLockedDrawed WHERE `id`=awardId; SELECT `drawed` INTO iOutmanDrawed FROM `qb_award_outman` WHERE `awardId`=awardId AND `userId`=userId LIMIT 0,1; SET iOutmanDrawed = iOutmanDrawed + 1; UPDATE `qb_award_outman` SET `drawed`= iOutmanDrawed WHERE `awardId` = awardId AND `userId`=userId; END [/code] 参数是 userId varchar(255),awardId bigint 在单独执行 [code="sql"] UPDATE `qb_award_outman` SET `drawed`= iOutmanDrawed WHERE `awardId` = 5 AND `userId`='AAA'; [/code] 这句的时候,能够正确执行 但是调用存储过程时, [code="sql"]call qb_award_outman('AAA',5)[/code] 这条语句的执行会忽略WHERE部分,更新全表的drawed字段。。。。 请问各位,有人知道这是为什么呢?谢谢了。。。

Hibernate JPA的异常java.sql.SQLException: ORA-00932: 数据类型不一致: 应为 TIMESTAMP, 但却获得 BINARY

使用的springboot,oracle数据库,查询的时候组装如下 ``` //Entity对应的字段如下 @CreatedDate @ApiModelProperty(value = "创建时间") private Date createTime; ``` ![图片说明](https://img-ask.csdn.net/upload/202004/25/1587815358_927072.png) ![图片说明](https://img-ask.csdn.net/upload/202004/26/1587887430_583910.png) 也试过between and 也是不行 在执行截图第40行的时候就报错了,还没有查数据库呢 后来还是自己写sql,字符串拼接的方式才查询的,但是和代码耦合比较高,还是想请教一下这个问题是哪里的问题?如何解决? 也可以直接帮我调试一下,先谢谢各位大神 具体报错 ![图片说明](https://img-ask.csdn.net/upload/202004/26/1587887243_414210.png)

java调用存储过程时的错误

``` public static int getNum(){ Connection conn = null; CallableStatement cs =null; try { conn = JdbcUtils.getConnection(); cs = conn.prepareCall("{call getNum(?)}"); cs.registerOutParameter(1, Types.INTEGER); cs.execute(); int num = cs.getInt(1); return num; } catch (Exception e) { e.printStackTrace(); }finally { try { if(cs!=null){ cs.close(); } } catch (SQLException e) { e.printStackTrace(); } JdbcUtils.free(null, null, conn); } return 0; } ``` 这样写总是返回0,如果改成下面那样就对了,这是为什么 ``` Connection conn = null; CallableStatement cs =null; try { conn = JdbcUtils.getConnection(); cs = conn.prepareCall("{call getNum(?)}"); cs.registerOutParameter(1, Types.INTEGER); ResultSet result=cs.executeQuery(); int num = 0; if(result.next()){ num = result.getInt("num"); } return num; } catch (Exception e) { e.printStackTrace(); }finally { try { if(cs!=null){ cs.close(); } } catch (SQLException e) { e.printStackTrace(); } JdbcUtils.free(null, null, conn); } return 0; } ```

Usage: mysql [OPTIONS] [database] -?, --help Display this help and exit. -I, --help Synonym for -? --auto-rehash Enable automatic rehashing. One doesn't need to use 'rehash' to get table and field completion, but startup and reconnecting may take a longer time. Disable with --disable-auto-rehash. (Defaults to on; use --skip-auto-rehash to disable.) -A, --no-auto-rehash No automatic rehashing. One has to use 'rehash' to get table and field completion. This gives a quicker start of mysql and disables rehashing on reconnect. --auto-vertical-output Automatically switch to vertical output mode if the result is wider than the terminal width. -B, --batch Don't use history file. Disable interactive behavior. (Enables --silent.) --character-sets-dir=name Directory for character set files. --column-type-info Display column type information. -c, --comments Preserve comments. Send comments to the server. The default is --skip-comments (discard comments), enable with --comments. -C, --compress Use compression in server/client protocol. -#, --debug[=#] This is a non-debug version. Catch this and exit. --debug-check Check memory and open file usage at exit. -T, --debug-info Print some debug info at exit. -D, --database=name Database to use. --default-character-set=name Set the default character set. --delimiter=name Delimiter to be used. -e, --execute=name Execute command and quit. (Disables --force and history file.) -E, --vertical Print the output of a query (rows) vertically. -f, --force Continue even if we get an SQL error. -G, --named-commands Enable named commands. Named commands mean this program's internal commands; see mysql> help . When enabled, the named commands can be used from any line of the query, otherwise only from the first line, before an enter. Disable with --disable-named-commands. This option is disabled by default. -i, --ignore-spaces Ignore space after function names. --init-command=name SQL Command to execute when connecting to MySQL server. Will automatically be re-executed when reconnecting. --local-infile Enable/disable LOAD DATA LOCAL INFILE. -b, --no-beep Turn off beep on error. -h, --host=name Connect to host. -H, --html Produce HTML output. -X, --xml Produce XML output. --line-numbers Write line numbers for errors. (Defaults to on; use --skip-line-numbers to disable.) -L, --skip-line-numbers Don't write line number for errors. -n, --unbuffered Flush buffer after each query. --column-names Write column names in results. (Defaults to on; use --skip-column-names to disable.) -N, --skip-column-names Don't write column names in results. --sigint-ignore Ignore SIGINT (CTRL-C). -o, --one-database Ignore statements except those that occur while the default database is the one named at the command line. -p, --password[=name] Password to use when connecting to server. If password is not given it's asked from the tty. -W, --pipe Use named pipes to connect to server. -P, --port=# Port number to use for connection or 0 for default to, in order of preference, my.cnf, $MYSQL_TCP_PORT, /etc/services, built-in default (3306). --prompt=name Set the mysql prompt to this value. --protocol=name The protocol to use for connection (tcp, socket, pipe, memory). -q, --quick Don't cache result, print it row by row. This may slow down the server if the output is suspended. Doesn't use history file. -r, --raw Write fields without conversion. Used with --batch. --reconnect Reconnect if the connection is lost. Disable with --disable-reconnect. This option is enabled by default. (Defaults to on; use --skip-reconnect to disable.) -s, --silent Be more silent. Print results with a tab as separator, each row on new line. --shared-memory-base-name=name Base name of shared memory. -S, --socket=name The socket file to use for connection. --ssl Enable SSL for connection (automatically enabled with other flags). --ssl-ca=name CA file in PEM format (check OpenSSL docs, implies --ssl). --ssl-capath=name CA directory (check OpenSSL docs, implies --ssl). --ssl-cert=name X509 cert in PEM format (implies --ssl). --ssl-cipher=name SSL cipher to use (implies --ssl). --ssl-key=name X509 key in PEM format (implies --ssl). --ssl-verify-server-cert Verify server's "Common Name" in its cert against hostname used when connecting. This option is disabled by default. -t, --table Output in table format. --tee=name Append everything into outfile. See interactive help (\h) also. Does not work in batch mode. Disable with --disable-tee. This option is disabled by default. -u, --user=name User for login if not current user. -U, --safe-updates Only allow UPDATE and DELETE that uses keys. -U, --i-am-a-dummy Synonym for option --safe-updates, -U. -v, --verbose Write more.
