solr 实现数据的删除和修改

修改主方法

public int saveContent(String enterpriseId, String enterpriseName, String lableType, String resouce, String pubDate,
String content) {

int state = 0;
LBHttpSolrServer server = SolrUtil.getSolrServer(ap.getEnterprisenewSolrUrl());
SolrQuery query = new SolrQuery();
query.set("q", "enterpriseId:" + enterpriseId);
try {
QueryResponse qr = server.query(query);
List<EnterpriseContentBean> contentList = qr.getBeans(EnterpriseContentBean.class);
// 设置需要保存的文章信息
for (EnterpriseContentBean bean : contentList) {
bean.setEnterpriseId(enterpriseId);
bean.setEnterpriseName(enterpriseName);
List<String> contents = new ArrayList<String>();
contents.add(content);
bean.setContent(contents);
bean.setPubDate(pubDate);
System.out.println("pubDate======>" + pubDate);
List<String> lableTypes = Arrays.asList(lableType.split(","));

bean.setLableType(lableTypes);
bean.setResource(resouce);
bean.setIsVisited_s("1");
}

server.addBeans(contentList);
server.commit();

} catch (SolrServerException e) {
state = 1;
System.out.println("修改solr数据报错");
e.printStackTrace();
} catch (IOException e) {
state = 1;
System.out.println("修改solr数据报错");
e.printStackTrace();
}
return state;

}

删除主方法

public int deletContent(String enterpriseId) {

LBHttpSolrServer server = SolrUtil.getSolrServer(ap.getEnterprisenewSolrUrl());
int state = 0;
try {
server.deleteById(enterpriseId);
server.commit();

} catch (SolrServerException e) {
state = 1;
System.out.println("删除solr数据报错");
e.printStackTrace();
} catch (IOException e) {
state = 1;
System.out.println("删除solr数据报错");
e.printStackTrace();
}

return state;
}
