java连接mysql错误
源码就是很简单的连接代码，没有错误。应该是驱动有问题
ERROR: index path not specified
Usage: java org.apache.lucene.index.CheckIndex pathToIndex [-fix] [-segment X] [-segment Y]
-fix: actually write a new segments_N file, removing any problematic segments
-segment X: only check the specified segments. This can be specified multiple
times, to check more than one segment, eg '-segment _2 -segment _a'.
You can't use this with the -fix option
**WARNING**: -fix should only be used on an emergency basis as it will cause
documents (perhaps many) to be permanently removed from the index. Always make
a backup copy of your index before running this! Do not run this tool on an index
that is actively being written to. You have been warned!
Run without -fix, this tool will open the index, report version information
and report any exceptions it hits and what action it would take if -fix were
specified. With -fix, this tool will remove any segments that have issues and
write a new segments_N file. This means all documents contained in the affected
segments will be removed.
This tool exits with exit code 1 if the index cannot be opened or has any
corruption, else 0.
这个错误为什么说索引没有找到？
