1.9 在solr 4 beta 下面创建索引的时候报错 about mmseg4j

[GoogleCodeExporter]

这个是因为Lucene 4.0 
beta里面Tokenizer的API改动的缘故，从之前的reset变成了现在的se
t，只需要把MMSegTokenizer类中reset方法的名字改成set去override掉�
��类的方法即可。

楼上方法试了不行啊。

不好意思，我没说清楚。
4.0Beta里，reset被改成了setReader，有两个类需要改动，一个是MM
SegTokenizerFactory（里面含有关于setReader的调用），另外一个是M
MSegTokenizer(需要override掉父类setReader的方法）。

MMSegTokenizer.java文件改动:
        //public void reset(Reader input) throws IOException {
        public void setReader(Reader input) throws IOException {
                //super.reset(input);
                mmSeg.reset(input);
        }

MMSegTokenizerFactory.java文件改动:

                        try {
                                //tokenizer.reset(input);
                                tokenizer.setReader(input);
                        } catch (IOException e) {
                                tokenizer = newTokenizer(input);
                                log.info("MMSegTokenizer.reset i/o error by:"+e.getMessage());
                        }

是这样吗。

//super.reset(input);
这个应该改为super.setReader(input);吧

   改后编译出错
    [javac] ~/tmp/mmseg4j/src/com/chenlb/mmseg4j/analysis/MMSegTokenizer.java:34: error: cannot find symbol
    [javac]             super.setReader(input);
    [javac]                  ^

MMSegTokenizer.java文件改动:
        //public void reset(Reader input) throws IOException {
        public void setReader(Reader input) throws IOException {
                super.setReader(input);
                mmSeg.reset(input);
        }
另外，你有引入Lucene 4.0 
Beta吗？如果有，不应该编译不过啊！

引入是不是就是该ivy.xml:

    <dependencies>^M
                <!-- solr/lucene -->^M
        <dependency org="org.apache.lucene" name="lucene-core" rev="4.0.0-BETA" conf="compile->master(*)"/>^M
        <dependency org="org.apache.lucene" name="lucene-analyzers-common" rev="4.0.0-BETA" conf="compile->master(*)"/>^M
        <dependency org="org.apache.lucene" name="lucene-queryparser" rev="4.0.0-BETA" conf="compile->master(*)"/>^M
        <dependency org="org.apache.solr" name="solr-core" rev="4.0.0-BETA" conf="compile->master(*)"/>^M

终于搞定了。

要吧lib下得ALPHA版本的jar文件删掉。

thanks.

我現在正在配置solr4正式版的時候也遇到這樣的問題 
有點不知道該怎麼去build 
不知道是否可以提供一下更改後編譯好的檔案呢？ 謝謝

照著上面的改成setReader會說無法override 
用原本的reset的話再solr那邊測試的時候會出現 Error occured 
while iterating over tokenstream 

請問該怎麼改？

[javac] Compiling 1 source file to /opt/mmseg4j/build/classes/java
    [javac] /opt/mmseg4j/src/com/chenlb/mmseg4j/analysis/MMSegTokenizer.java:32: setReader(java.io.Reader) in com.chenlb.mmseg4j.analysis.MMSegTokenizer cannot override setReader(java.io.Reader) in org.apache.lucene.analysis.Tokenizer; overridden method is final
    [javac]     public void setReader(Reader input) throws IOException {
    [javac]                 ^
    [javac] 1 error

请将你的MMSegTokenizer类的 incrementToken 
方法标注成final。否则在debug模式下会抛异常。

现在的正式版里，setReader已经是final，不能被override了，请作�

我也遇到这个问题了,还以为是lucene4和solr4不兼容呢, 
狂google了一圈. 还好找到了这个帖子. 麻烦作者更新下发布包.

谢谢eddie和dota的讨论, 我把solr, 
lucene都改称4.0.0正式版编译了一下. 自己测试能用了. 
付上编译后的jar包和大家分享.

solr4.6+mmseg4j1.9集成时报错

想问一下你们在修改代码然后重新编译项目。那么源代码是��

使用 2.0.0
