Oracle数据库中有一个字段是CLOB类型，使用java 解析.
1.使用java解析clob类型内容
public String clobToString(Clob c) {
StringBuffer sb = new StringBuffer(1024);
Reader instream = null;
try {
instream = c.getCharacterStream();
char[] buffer = new char[(int) c.length()];
int length = 0;
while ((length = instream.read(buffer)) != -1) {
sb.append(buffer, 0, length);
}
} catch (Exception ex) {
ex.printStackTrace();
return null;
} finally {
try {
if (instream != null)
instream.close();
} catch (Exception dx) {
instream = null;
}
}
return sb.toString();
}
if(pageObject.getResultList() != null && pageObject.getResultList().size() > 0){
for(int i=0,j=pageObject.getResultList().size(); i < j;i++){
Map<String,Object> maps = (Map<String, Object>) pageObject.getResultList().get(i);
maps.put("DISPATCHINGRULESNAME",this.clobToString((Clob) maps.get("DISPATCHINGRULESNAME"))); //这里将Clob类型转化成字符串,调用clobToString((Clob)方法
}
}
2.使用oracle函数 to_char(字段)
select to_char(t.billName) as billName from T_CC_SHARE_DISPATCH_RULE t
