小编j4n*_*53n的帖子

我在 gitlab 中创建了一个管道，其中

image:
  name: hashicorp/terraform:light
  entrypoint:
    - '/usr/bin/env'
    - 'PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin'

variables:
  PLAN: dbrest.tfplan
  STATE: dbrest.tfstate

cache:
  paths:
    - .terraform

before_script:
  - terraform --version
  - terraform init

stages:
  - validate
  - build
  - deploy
  - destroy

validate:
  stage: validate
  script:
    - terraform validate

plan:
  stage: build
  script:
    - terraform plan -state=$STATE -out=$PLAN
  artifacts:
    name: plan
    paths:
      - $PLAN
      - $STATE

apply:
  stage: deploy
  environment:
    name: production
  script:
    - terraform apply -state=$STATE -input=false $PLAN
    - terraform state show aws_instance.bastion
  dependencies:
    - …

我使用 terraform 创建 EC2 实例，并user_data使用/var/lib/cloud/scripts/per-once. 这没有执行 - 我现在的问题是：cloud-init 之前运行过吗user_data？

===编辑===

对 Dude0001 非常有帮助的答案的更长回复：

我现在尝试了以下方法 - 这是我的user_data：

#!/bin/bash
cat >/var/lib/cloud/scripts/per-once/install_mysql <<!
#cloud-config

package_update: true

packages:
  - mysql-server

!

cat >>/root/.bashrc <<!
set -o vi
unalias -a
alias ll='ls -lp'
!

cat >>/home/admin/.bashrc <<!
set -o vi
unalias -a
alias ll='ls -lp'
!

cat /root/.vimrc <<!
set t_ti= t_te=
set compatible
set expandtab ts=2 sw=2 ai
!

cat >/home/admin/.vimrc <<!
set t_ti= t_te=
set …

简而言之,首先 - 我收到此异常消息:

serverError: class javax.faces.el.EvaluationException Duplicate annotation for class: interface javax.validation.constraints.Size: @javax.validation.constraints.Size(groups=[], min=0, message={javax.validation.constraints.Size.message}, payload=[], max=128)

我的代码由一个表的实体类,一个EJB,一个"业务类"和一个JSF页面组成; 当我调用EntityManager.merge()时发生异常.其中只有1个注释'max = 128':

@Size(max = 128)
@Column(name = "name")
private String name;

唯一具有重复注释的地方是:

@Entity
@Table(name = "attributes", schema = "office_db")
@XmlRootElement
@NamedQueries({
    @NamedQuery(name = "Attributes.findAll", query = "SELECT a FROM Attributes a"),
    @NamedQuery(name = "Attributes.findById", query = "SELECT a FROM Attributes a WHERE a.id = :id"),
    @NamedQuery(name = "Attributes.findByName", query = "SELECT a FROM Attributes a WHERE a.name = :name"),
    @NamedQuery(name = …

我有一个表，其中ga_sum_1有一列。created_timestamp当我从 mysql 命令行执行以下查询时：

mysql> select max(created_timestamp) from ga_sum_1;
+------------------------+
| max(created_timestamp) |
+------------------------+
| 2017-11-05 00:59:55    |
+------------------------+
1 row in set (0.00 sec)

如果我从一个非常简单的存储过程中执行相同的操作：

delimiter //
create procedure test()
begin
  select max(created_timestamp) from ga_sum_1;
end//
delimiter ;

mysql> call test();
+------------------------+
| max(created_timestamp) |
+------------------------+
| 2017-11-05 00:59:55    |
+------------------------+
1 row in set (0.00 sec)

但是，当我在存储过程中进行同样的操作时：

drop procedure if exists test;

delimiter //

create procedure test()
begin
  declare cursor_end condition for sqlstate '02000';
  declare …

我定义了以下简单的管道：

image:
  name: hashicorp/terraform:light
  entrypoint:
    - '/usr/bin/env'
    - 'PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin'

variables:
  PLAN: dbrest.tfplan
  STATE: dbrest.tfstate

cache:
  paths:
    - .terraform

before_script:
  - terraform --version
  - terraform init

stages:
  - validate
  - build
  - deploy
  - destroy

简介： 我一直在开发一个带有文档列表的有点复杂的 JSF 表单，现在想要在该列表的每一行中添加一个按钮，这将允许您下载文档文件。Primefaces 对此提供了一个有吸引力的解决方案，因此我逐渐将整个页面转换为使用 primefaces，但现在我刚刚转换了文档表 - 尽管看起来很奇怪，但效果很好。我的问题是，当我添加 , 时p:commandButton，我遇到了一个例外，而且我什至不知道它意味着什么 - 据我所知，我正在遵循我能够找到的示例，包括 primefaces 的展示：

org.primefaces.component.column.Column cannot be cast to javax.faces.component.ActionSource

这是表的详细信息

<h:form id="doclistform">
    <p:dataTable value="#{documentsController.documentList}" var="doclst"
                 id="doclist">
        <!-- innocent columns -->
        <p:column>
            <f:facet name="header">
                <h:outputText value="Download"/>
            </f:facet>
            <p:fileDownload value="#{doclst.docfile}"/>
        </p:column>
    </p:dataTable>
</h:form>
