JPA標(biāo)準(zhǔn)＋HIBERNATE實(shí)現(xiàn)＋SPINRG揉和

感覺(jué)這3個(gè)東東比較好，就查例子，及SPRING文檔做了以下配置。

類映射就用JPA的annotations好，本來(lái)transaction也應(yīng)該用的，但后來(lái)發(fā)現(xiàn)aop+advise這種定義方式方便，就先用它，隨時(shí)可以改過(guò)來(lái)。這些定義都挺簡(jiǎn)單，看一下SPRING的文檔就都清楚了，而且看最新文檔還有個(gè)好處，知道最新的寫法是什么。

將transaction定義在MANAGER上，DAO就注入到它里面。

還有一個(gè)暈的地方：

Persistence.xml這個(gè)文件就算不用也要定義，它是用來(lái)放映射的hbm.xml或者是被annotation的類名的，但我發(fā)現(xiàn)其實(shí)寫了也沒(méi)用，它好像會(huì)自動(dòng)去搜索hbm.xml以及有annotations的類，自動(dòng)加到EntityManager里。我只有把不用的hbm.xml刪除掉它才會(huì)不加。這一點(diǎn)相當(dāng)奇怪，試了八百多次，也沒(méi)啥心思研究了，刪除了事。

DAO代碼很簡(jiǎn)單，從JpaDaoSupport派生類來(lái)處理，看不見(jiàn)transactions的那些代碼，全部在SPRING的定義里放到manager里去了：

publicclass JpaGenericDAO extends JpaDaoSupport {

       protectedfinal Logger logger = LoggerFactory.getLogger(getClass());

       publicvoid create(T entity) {

              Assert.notNull(entity);

              logger.info("saving {} instance", className);

              getJpaTemplate().persist(entity);

              logger.info("save successful");

       }

}

搭建MAVEN2的內(nèi)網(wǎng)服務(wù)器：設(shè)置一個(gè)目錄在WEB服務(wù)上可以訪問(wèn)

在/etc/apache2/conf.d下新建配置文件，內(nèi)容如下：

Alias /maven2 /maven2

<Directory /maven2>

        Options +FollowSymLinks Indexes

        AllowOverride None

        order allow,deny

        allow from all

</Directory>

這里關(guān)鍵是Indexes選項(xiàng)表示可以列出目錄。

另外，把httpd的運(yùn)行用戶加入這個(gè)目錄的owner所在的一個(gè)組，并且組的讀屬性是開(kāi)的。

設(shè)置服務(wù)器地址：

在C:"WINDOWS"system32"drivers"etc"hosts文件加入ebnms指向內(nèi)網(wǎng)服務(wù)器，然后將第一項(xiàng)repo指向它：

              <repository>

                     <id>artifactory</id>

                     <name>artifactory at my server</name>

                     <url>http://ebnms/maven2</url>

                     <snapshots>

                            <enabled>true</enabled>

                            <updatePolicy>never</updatePolicy>

                     </snapshots>

              </repository>

MYSQL可以被外部機(jī)器連接

修改CONFIG文件為綁定全網(wǎng)端口：

bind-address            = 0.0.0.0

本機(jī)通過(guò)ROOT連接上后，執(zhí)行命令給權(quán)限：

GRANT ALL PRIVILEGES ON *.* TO root@192.168.1.99 IDENTIFIED BY '78317';

試登陸：

mysql -u root -h 192.168.1.17 –p

修改密碼：
SET PASSWORD FOR root@'172.19.149.52' = PASSWORD('78317');

cannot connect to VM錯(cuò)誤

左提示右提示就是這個(gè)錯(cuò)，找了半天是Kaspersky防火墻的問(wèn)題，其實(shí)一早我就懷疑是它，但只是停用了試了下，錯(cuò)誤依舊，后來(lái)試了一天又試回來(lái)，發(fā)現(xiàn)要把防火墻的過(guò)濾級(jí)別設(shè)置成最低就可以了通了，暈啊暈，還讓我懷疑是不是JAR沖突。
