python引用jar包,找不到类

[JinmingZhao]

环境: python2.7 jdk1.6.0_45
jar 包版本: tree_split-1.5.jar 和 ansj_seg-5.1.6.jar

代码:
`#!coding=utf-8
import jpype
import os
jvmPath = '/usr/lib/java/jdk1.6.0_45/jre/lib/amd64/server/libjvm.so'
print jvmPath

jars_dir = '/mnt/data/pretrained_models/word2vec_models/jars4ansj'
jars = [os.path.join(jars_dir, 'ansj_seg-5.1.6.jar'), os.path.join(jars_dir, 'tree_split-1.5.jar')]

jvm_cp = "-Djava.class.path={}".format(':'.join(jars))
jpype.startJVM(jvmPath, "-ea", jvm_cp)
print "-----------------"
JDClass = jpype.JClass('org.ansj.splitWord.analysis.NlpAnalysis')
jd = JDClass()
jd.parse("怎么这么麻烦")

jpype.shutdownJVM()`

报错信息:
/usr/lib/java/jdk1.6.0_45/jre/lib/amd64/server/libjvm.so
Traceback (most recent call last):
File "ansj_segment.py", line 13, in
JDClass = jpype.JClass('org.ansj.splitWord.analysis.NlpAnalysis')
File "/home/jinmming/anaconda2/lib/python2.7/site-packages/jpype/_jclass.py", line 73, in JClass
raise _RUNTIMEEXCEPTION.PYEXC("Class %s not found" % name)
jpype._jexception.RuntimeExceptionPyRaisable: java.lang.RuntimeException: Class org.ansj.splitWord.analysis.NlpAnalysis not found

之前看报错是由于jdk版本, 后来由jdk1.8换到jdk1.6还是不行, 求大神指教, 看看还有什么遗漏的细节?
jar包的导入没有问题, 就是寻找类的时候报错了.

解决了, 感谢作者开源, 提供给对于 java不熟, 不想用jiaba分词, 对 ansj_seg 念念不忘的同学们一个 python 一个解决方案:
环境: python2.7 jdk1.8.0_161 tree_split-1.5.jar, nlp-lang-1.7.7.jar和 ansj_seg-5.1.6.jar
对于环境, 虽然文档写的jdk1.6, 但是可能是之前的版本, 看最新的jar包的mainfest文件中有jdk的最新版本.
踩了很多坑, 刚开始一直找不到类, 弄了大半天, 各种试jdk版本.
第一注意jdk版本:
第二注意所有依赖包, 看源码发现会引用nlp-lang里面的类
第三注意函数是调用父类 Analysis的方法名称.

`#!coding=utf-8
import jpype
import os
jvmPath = '/usr/lib/java/jdk1.8.0_161/jre/lib/amd64/server/libjvm.so'
print jvmPath

jars_dir = '/mnt/data/pretrained_models/word2vec_models/jars4ansj'
jars = [os.path.join(jars_dir, 'ansj_seg-5.1.6.jar'), os.path.join(jars_dir, 'nlp-lang-1.7.7.jar'), os.path.join(jars_dir, 'tree_split-1.5.jar')]
jvm_cp = "-Djava.class.path={}".format(':'.join(jars))
jpype.startJVM(jvmPath, "-ea", jvm_cp)
SegModel = jpype.JClass('org.ansj.splitWord.analysis.ToAnalysis')
jd = SegModel()
print(jd.parseStr("怎么这么麻烦"))

jpype.shutdownJVM()`

已解决：
将jvm_cp = "-Djava.class.path={}".format('：'.join(jars))中的冒号转为分号就可以了jvm_cp = "-Djava.class.path={}".format(';'.join(jars))
