Question

我正在尝试更新solr中的文档。逻辑所在的方法是用两个不同的tomcats编写的，即Tomcat v6.0和Tomcat v8.0，但基本上是相同的代码。后来的版本工作正常，但前者不是。

Solr托管版本为v4.0x
v6.0包含apache-solr-solrj-3.6.0 jar
v8.0包含solr-solrj-4.10.3 jar。

以下是我处理Tomcat v6

时获得的堆栈跟踪

org.apache.solr.client.solrj.SolrServerException：http://10.210.16.66:8084/solr/mydoc处的服务器返回非正常状态：400，消息：错误请求在org.apache.solr.client.solrj.impl.HttpSolrServer.request（HttpSolrServer.java:328）在org.apache.solr.client.solrj.impl.HttpSolrServer.request（HttpSolrServer.java:211）在org.apache.solr.client.solrj.request.AbstractUpdateRequest.process（AbstractUpdateRequest.java:105）在org.apache.solr.client.solrj.SolrServer.add（SolrServer.java:121） at mypackage.solr.SolrPortal.addUpdateRecordsToSolr（SolrPortal.java:171）在mypackage.updateFAQSolr（PortalDocumentsDAO.java:1761） at mypackage.saveFaqlogs（PortalDocumentsDAO.java:1230）在org.apache.jsp.jsp.saveFaqlog_jsp._jspService（saveFaqlog_jsp.java:72）在org.apache.jasper.runtime.HttpJspBase.service（HttpJspBase.java:70）在javax.servlet.http.HttpServlet.service（HttpServlet.java:723）在org.apache.jasper.servlet.JspServletWrapper.service（JspServletWrapper.java:388）在org.apache.jasper.servlet.JspServlet.serviceJspFile（JspServlet.java:313）在org.apache.jasper.servlet.JspServlet.service（JspServlet.java:260）在javax.servlet.http.HttpServlet.service（HttpServlet.java:723）在org.apache.catalina.core.ApplicationFilterChain.internalDoFilter（ApplicationFilterChain.java:290）在org.apache.catalina.core.ApplicationFilterChain.doFilter（ApplicationFilterChain.java:206） at mypackage.servlet.SessionFilterAll.doFilter（SessionFilterAll.java:79）在org.apache.catalina.core.ApplicationFilterChain.internalDoFilter（ApplicationFilterChain.java:235）在org.apache.catalina.core.ApplicationFilterChain.doFilter（ApplicationFilterChain.java:206）在com.myecw.servlet.JspFilter.doFilter（JspFilter.java:33）在org.apache.catalina.core.ApplicationFilterChain.internalDoFilter（ApplicationFilterChain.java:235）在org.apache.catalina.core.ApplicationFilterChain.doFilter（ApplicationFilterChain.java:206）在org.apache.catalina.core.StandardWrapperValve.invoke（StandardWrapperValve.java:233） at org.apache.catalina.core.StandardContextValve.invoke（StandardContextValve.java:191）在org.apache.catalina.authenticator.AuthenticatorBase.invoke（AuthenticatorBase.java:470）在org.apache.catalina.core.StandardHostValve.invoke（StandardHostValve.java:127）在org.apache.catalina.valves.ErrorReportValve.invoke（ErrorReportValve.java:103）在org.apache.catalina.core.StandardEngineValve.invoke（StandardEngineValve.java:109）在org.apache.catalina.connector.CoyoteAdapter.service（CoyoteAdapter.java:293）在org.apache.coyote.http11.Http11AprProcessor.process（Http11AprProcessor.java:879）在org.apache.coyote.http11.Http11AprProtocol $ Http11ConnectionHandler.process（Http11AprProtocol.java:617）在org.apache.tomcat.util.net.AprEndpoint $ Worker.run（AprEndpoint.java:1760）在java.lang.Thread.run（Thread.java:619）

以下是solr

中的错误

org.apache.solr.common.SolrException：不支持的ContentType：application / octet-stream不在：[application / xml，text / csv，text / json，application / csv，application / javabin， text / xml，application / json]

代码：

public void updateFAQSolr(){

    StringBuilder str = new StringBuilder();
    str.append(" My query to update data ");
    System.out.println(" NEW solr query is -> " + str.toString());
    SolrPortal se = new SolrPortal("faqdata");

    se.addUpdateRecordsToSolr(str.toString());
}

public void addUpdateRecordsToSolr(String query) {


    RootSlave rootslave =  null;
    Connection con =  null;
    PreparedStatement pstmt = null;
    ResultSet rs = null;
    ResultSetMetaData rsmd = null;
    try {

        rootslave = new RootSlave();
        rootslave.initconnection();
        con = rootslave.con;
        pstmt = con.prepareStatement(query);
        rs = pstmt.executeQuery();
        rsmd = rs.getMetaData();
        int colCount = rsmd.getColumnCount();
        while(rs.next()) {
            SolrInputDocument doc = new SolrInputDocument();
            for(int i=1;i<colCount;i++) {
                String label = rsmd.getColumnLabel(i);
                doc.addField(label, rs.getObject(i));
            }
            System.out.println("content type is ->> "+getContentType());
            solrServer.add(doc,10000);
        }
        solrServer.commit();

    }catch(Exception e) {
        e.printStackTrace();
        EmgrLog.AppendExceptionToLog(e);
    }finally {
        RootSlave.close(rs);
        RootSlave.close(pstmt);
        RootSlave.close(con);
    }
}

PS：内容类型明确设置为application\json

编辑：

Tomcat 6.0 Document使用solr-solrj-4.10.3输出

SolrInputDocument[{views=views(1.0)={1585}}}]

Tomcat 8.0 Document使用apache-solr-solrj-3.6.0输出

  SolrInputDocument(fields: [views=1585])

Solr更新文档 - 错误请求异常
