小编auh*_*man的帖子

我试图在javadoc中的代码标记内放置一个链接.以下是我的尝试.

/**
* This method builds XML.
* <pre>
* {@code
* <Person {@link #companyId}='1234'/>
* }
* </pre>
**/

但是在生成的Javadoc中,链接不存在.字符串{@link #companyId}='1234'就是这样.

• 是否允许嵌套javadoc标签？
• 有没有办法在代码中添加链接？

如何使用aws控制台或aws cli手动强制丢弃集群中的aws lambda函数以进行开发和测试？

我创建了一个流口水文件 PersonTotalAccountsBalance.drl 如下。我是规则引擎世界的初学者。

package com.auhuman.rules;

import com.auhuman.Person;
import com.auhuman.Account;

function float getTotalBalance(Person person) {
     float totalBalance = 0;
     for (Account account : person.getAccounts()){
         totalBalance += account.getBalance();
     }
     return totalBalance;
}

rule "PersonTotalAccountsBalance"
    when
        $node : Person(active == true)
    then
        float totalBalance = getTotalBalance($node)

        modify($node) {
           setTotalBalance(totalBalance);
        }
end

编译后我收到以下错误

Unable to compile the file: PersonTotalAccountsBalance.drl. Errors = [Unable to find @positional field 0 for class Person
 : [Rule name='PersonTotalAccountsBalance']
]

我正在将 ORM 框架从 Hibernate 切换到 OpenJPA。

在 Hibernate 中，我们可以使用 @ColumnTransformer 注释字段，如下所示。

@Column(name = "EMP_NAME", length = 4000)
@ColumnTransformer(
        read = "pgp_pub_decrypt(emp_name::bytea,dearmor('"+key1+"'))",
        write = "pgp_pub_encrypt(?, dearmor('"+key2+"'))"
)
private String empName;

如何在 OpenJPA 中执行相同操作

运行我的 Perl 脚本时出现以下错误。

Can't locate Date/Parse.pm in @INC (@INC contains: /opt/local/lib/perl5/site_perl/5.16.1/darwin-thread-multi-2level /opt/local/lib/perl5/site_perl/5.16.1 /opt/local/lib/perl5/vendor_perl/5.16.1/darwin-thread-multi-2level /opt/local/lib/perl5/vendor_perl/5.16.1 /opt/local/lib/perl5/5.16.1/darwin-thread-multi-2level /opt/local/lib/perl5/5.16.1 /opt/local/lib/perl5/site_perl /opt/local/lib/perl5/vendor_perl .) at ../../tools/replace_tenant_json_data.pl line 27.\nBEGIN failed--compilation aborted at ../../tools/replace_tenant_json_data.pl line 27.

从上面的错误我推断 perl 查找模块的错误目录。\n正确的目录是 /System/Library/Perl/5.16

命令 env \xe2\x80\x93I perl \xe2\x80\x93V 与 perl \xe2\x80\x93V 不同

当变量说testVar被赋值为findOne的结果时,它的可用性是无穷无尽的.但是,分配了find()可用性结果的变量只有一次.下面是命令提示符转储

> var testVar = db.basic.findOne()
> testVar
{ "_id" : ObjectId("52abd2737164a542e93f1ebe"), "name" : "MongoDB" }
> testVar
{ "_id" : ObjectId("52abd2737164a542e93f1ebe"), "name" : "MongoDB" }
> testVar
{ "_id" : ObjectId("52abd2737164a542e93f1ebe"), "name" : "MongoDB" }


> var testVar = db.basic.find({"name":"MongoDB"})
> testVar
{ "_id" : ObjectId("52abd2737164a542e93f1ebe"), "name" : "MongoDB" }
> testVar
> testVar
