SSH2中，直接獲取SEQUENCE的NEXTVAL ，使用OracleSequenceMaxValueIncrementer

SSH2中，直接獲取SEQUENCE的NEXTVAL

使用Spring的類 org.springframework.jdbc.support.incrementer.OracleSequenceMaxValueIncrementer

Spring配置文件：

1     <bean id="userDao" class="com.xx.dao.impl.UserDAOImpl">
2         <property name="sessionFactory" ref="sessionFactory" />
3         <property name="seqGenerator" ref="seqDispGenerator"></property>
5     </bean>
6
7     <bean id="seqDispGenerator" class="org.springframework.jdbc.support.incrementer.OracleSequenceMaxValueIncrementer">
8         <property name="dataSource" ref="dataSource"></property>
9         <property name="incrementerName" ><value>SEQ_DISP_ID</value></property>
10     </bean>

UserDAOImpl.java中引用：

private OracleSequenceMaxValueIncrementer seqGenerator;



    /**
     * @return the seqGenerator
     */
    public OracleSequenceMaxValueIncrementer getSeqGenerator() {
        return seqGenerator;
    }

    /**
     * @param seqGenerator the seqGenerator to set
     */
    public void setSeqGenerator(OracleSequenceMaxValueIncrementer seqGenerator) {
        this.seqGenerator = seqGenerator;
    }

UserDAOImpl.java中調(diào)用：

1 System.out.println("---------------------- this.seqGenerator().nextIntValue="+this.seqGenerator.nextIntValue());

如何運行打開windows下面的system系統(tǒng)屬性

Description:.

To bring up System Properties:

1. Click Start and then Control Panel. From the Control Panel, double click System.

2. Another way to bring up this box is to right click the My Computer on your desktop. From the menu, select Properties.

Solution:

1. 參考http://www.passcape.com/windows_run_commands

除了這兩種方式外，還有一種直接運行system32下面的命令文件方式

運行C:"WINDOWS"system32 下面的sysdm.cpl。

注解@Override 報錯

Description: @Override該標(biāo)記是為了增強程序在編譯時候的檢查，JDK1.5下，如果該方法并不是一個覆蓋父類的方法，在編譯時編譯器就會報告錯誤。

Analisys:

1

public class A {
2

public void method(int i) {
3

}
4

}
5

6

public class B extends A {
7

@Override
8

public void method(int i) {
9

}
10

11

//如果如下定義，就會在編譯時出現(xiàn)一個錯誤，因為不是覆蓋父類的方法
12

@Override
13

public void method(int i, String p_Str) {
14

}
15

16

}

JDK1.6正常，支持對接口的實現(xiàn)的@Override

3

public void method(int i) {
4

5

}
6

7

安裝Oracle Client 9/10后,Eclipse 啟動時的JDK/JVM問題

Description:
Incompatible JVM- Version 1.4.2_03 of the JVM is not suitable for th is product. Version:1.5 or greater is required.

Analisys:

安裝Oracle Client 9/10后, Path 被設(shè)置為Oracle自帶的JDK 1.4, 啟動高版本Eclipse(eclipse-jee-helios-SR1-win32.exe)時,　就默認用Oracle自帶的JDK 1.4，這樣就會有問題。

Solution:

多種解決方案

1. 修改環(huán)境變量：　Path = %JAVA_HOME%"bin;%PATH%
權(quán)限的問題，我沒有選擇這個解決方案。

2. 修改Eclipse啟動項：修改Eclipse快捷方式的屬性里面的目標(biāo)：　
D:"tool"eclipse-jee-helios-SR1-win32"eclipse"eclipse.exe　-vm "C:"Program Files"Java"jdk1.5.0_05"bin"javaw.exe"

Eclipse 報錯: class Implement Interface-> @Override function -> must override a superclass

代碼:
Class XX implements InterfaceYY{
    @override
    function funcXX(){
    }
}

Eclipse報錯: must override a superclass implements

Analisys:
1. @override 可以針對 Interface; 不過最好用另外一個annotation: @implement
2. java5 java6 支持泛型
3. eclipse 里面的compile版本是JDK 5

Solution:
eclipse 里面的compile版本是JDK 5 -> 改成 JDK6
