JDBC执行匿名块
mytables.sql

declare
    num int:=0;
begin
    dbms_output.PUT_LINE('--------------------start pro[OracleTools]-----------------------');
	--getStrBeforeLine
    select count(*) into num from mytables  where dict_id=10;
    if num>0 then
       update mytables set STATE='001',DESCRIPTION='',DISPLAY_INDEX=1,EDIT_USER=NULL,LAST_OPER_ID=NULL,CREATE_USER='admin',EDIT_DATE=NULL,DICT_NAME='文本',DICT_CODE='001',CREATE_DATE=NULL,DICT_TYPE_CODE='BSC_ANALYSIS_ITEM_TYPE',VERSION_NUM=NULL where dict_id=10;

要用StringBuffer来存放匿名块文件的代码，读取每一行的时候，记得加上回车符号。
然后：
PreparedStatement st = conn.prepareStatement(sb.toString());
st.execute();
调用匿名块是运行参数的，具体看API

package com.geosun.main;

import java.io.BufferedReader;
import java.io.FileReader;
import java.sql.Connection;
import java.sql.PreparedStatement;

import com.geosun.conf.DBUtils;

public class ProcessUnNameSQL {

	public static StringBuffer readFile(String filePath){
		BufferedReader reader = null;
		StringBuffer sb = new StringBuffer();
		try {
			reader = new BufferedReader(new FileReader(filePath));
			String line = reader.readLine();
			while(line!=null){
				sb.append(line+"\n");
				line = reader.readLine();
			}
		} catch (Exception e) {
			e.printStackTrace();
			throw new RuntimeException(e);
		}
		System.out.println(sb.toString());
		return sb;
	}
	public static void process(Connection conn, String filePath){
		StringBuffer sb = readFile(filePath);
		try {
			conn.setAutoCommit(false);
			PreparedStatement st = conn.prepareStatement(sb.toString());
			System.out.println("Start Process");
			st.execute();
			conn.commit();
			System.out.println("Process success.");
		} catch (Exception e) {
			// TODO: handle exception
			e.printStackTrace();
			throw new RuntimeException(e);
		}
	}
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		try {
			Connection conn = DBUtils.getNewConn("jdbc:oracle:thin:@localhost:1521:orcl", "aaa", "aaa", "oracle.jdbc.driver.OracleDriver");
			String filePath="D:\mytables.sql";
			process(conn, filePath);
			conn.close();
		} catch (Exception e) {
			// TODO: handle exception
			e.printStackTrace();
		}
	}

}
