我尝试使用 SchemaSpy 分析 DB2 数据库，但收到警告“连接失败”。我试过这样：

java -jar schemaspy-6.0.0.jar -configFile schemaspy.properties --logging.pattern.console="%d{HH:mm:ss.SSS} %clr(%-5level) - %msg%n" --logging.level.org.schemaspy=TRACE

（在https://github.com/schemaspy/schemaspy/issues/250上找到了日志记录部分）

.properties 文件如下所示：

schemaspy.t=db2
schemaspy.dp=C:\tmp\db2jcc.jar
schemaspy.host=**host**
schemaspy.port=50000
schemaspy.db=**db**
schemaspy.u=**user**
schemaspy.p=**password**
schemaspy.o=D:\**\schemaspy-output\
schemaspy.s=**schema**

我得到的错误是：

    14:24:20.297 DEBUG - Unable to find driverClass COM.ibm.db2.jdbc.app.DB2Driver'
    14:24:20.308 WARN  - Connection Failure

我猜，错误来自错误的类路径？但是我该如何解决这个问题？我试图更改 db2.properties 中的行

driver=COM.ibm.db2.jdbc.app.DB2Driver

至

driver=COM.ibm.db2.jcc.DB2Driver

，因为我从驱动程序的 .jar 文件中提取了这个类路径，但它没有帮助。

这对我有用 db2jcc.jar

# type of database. Run with -dbhelp for details
schemaspy.t=db2
# optional path to alternative jdbc drivers.
schemaspy.dp=/lib/db2jcc.jar
# database properties: host, port number, name user, password
schemaspy.host=xxxxxx
schemaspy.port=xxxxx
schemaspy.db=xxx
schemaspy.u=xx
schemaspy.p=xx
# output dir to save generated files
schemaspy.o=/output
# db scheme for which generate diagrams
schemaspy.s=xxxx
driver=com.ibm.db2.jcc.DB2Driver
connectionSpec=jdbc:db2://xxx.xx.x.xxx:[PORT]/[DBNAME]
schemaspy.cat=%

使用的命令：

java -jar schemaspy-6.1.0.jar -configFile db2.properties  --logging.pattern.console="%d{HH:mm:ss.SSS} %clr(%-5level) - %msg%n" --logging.level.org.schemaspy=TRACE
