plsql调用java方法（举例） 一、编写java源文件 public class Test { public static void main(String args[]) { System.out.println("test"); } public static String returnString(String strTest) { return "return:" + strTest; } } 二、装载Java代码及类到Oracle8i数据库中 loadjava -user aipay/payai@aipay -o -v -f -r Test.java 三、发行Java，生成调用说明 sqlplus aipay/payai@aipay 登陆 CREATE OR REPLACE FUNCTION fc_java_test (v_test VARCHAR2) RETURN VARCHAR2 AS LANGUAGE JAVA NAME 'Test.returnString(java.lang.String) return java.lang.String'; / 四、测试 sqlplus aipay/payai@aipay 登陆 select fc_java_test('test') from dual; =================================================================================================== plsql调用java方法（实际操作） loadjava -user aipay/payai@aipay -o -v -f -r com/aipay/webapp/util/DesUtil.java CREATE OR REPLACE FUNCTION fc_java_DesUtil_decipher2 (v_passwd VARCHAR2,v_passwd_length PLS_INTEGER) RETURN VARCHAR2 AS LANGUAGE JAVA NAME 'com.aipay.webapp.util.DesUtil.decipher2(java.lang.String,java.lang.int) return java.lang.String'; / select fc_java_DesUtil_decipher2('9bddcff77b68a916',16) from dual; CREATE OR REPLACE FUNCTION fc_java_DesUtil_cipher2 (v_passwd VARCHAR2,v_passwd_length PLS_INTEGER) RETURN VARCHAR2 AS LANGUAGE JAVA NAME 'com.aipay.webapp.util.DesUtil.cipher2(java.lang.String,java.lang.int) return java.lang.String'; / select fc_java_DesUtil_cipher2('test',4) from dual; CREATE OR REPLACE FUNCTION fc_java_DesUtil_returnString (v_string VARCHAR2) RETURN VARCHAR2 AS LANGUAGE JAVA NAME 'com.aipay.webapp.util.DesUtil.returnString(java.lang.String) return java.lang.String'; / select fc_java_DesUtil_returnString('test') from dual; CREATE OR REPLACE procedure fc_java_DesUtil AS LANGUAGE JAVA NAME 'com.aipay.webapp.util.DesUtil.main(java.lang.String[])'; / set serveroutput on size 5000 call dbms_java.set_output(5000); execute fc_java_DesUtil; call fc_java_DesUtil();
