如何部署一个 webapp 并创建它的资源 [英] how to deploy a webapp and create its resources

问题描述

在 glassfish 4 上部署myapp.war"之前，我必须

before deploy "myapp.war" on glassfish 4 i have to

1. 创建 jdbc 连接池(/WEB-INF/glassfish-resources.xml -> jdbc-connection-pool 本身不起作用... asadmin 很好)
2. 为池创建 jdbc 资源(/WEB-INF/glassfish-resources.xml -> jdbc-resource 同上)
3. 创建 auth-realm(没有自动，现在使用 asadmin)
4. 创建模式(peristence.xml -> property javax.persistence.schema-generation.create-database-schemas，但是是假的)
5. 创建表(persistence.xml -> `create-tables'，虽然不完美但至少可以工作)

1. create jdbc connection pool (/WEB-INF/glassfish-resources.xml -> jdbc-connection-pool does not work by itself... fine from asadmin)
2. create jdbc resource for pool (/WEB-INF/glassfish-resources.xml -> jdbc-resource same as above)
3. create auth-realm (nothing auto, using asadmin for now)
4. create schema (peristence.xml -> property javax.persistence.schema-generation.create-database-schemas, but is bogus)
5. create tables (persistence.xml -> `create-tables', not perfect but at least it works)

现在我在做:

1. 在/tmp/install 上上传myapp.war"、glassfish-resources.xml"
2. asadmin add-resources ...
3. asadmin create-auth-realm ...
4. asadmin deploy ...
5. asadmin 禁用 myapp ...
6. nano/.../glassfish/applications/myapp/WEB-INF/classes/META-INF/persistence.xml
7. 注释几行，ctrl+o、enter、ctrl+x、enter
8. asadmin enable myapp ...
9. rm -Rf/tmp/install

在没有其他建议的情况下，我打算:

and without other suggestion i'm planning to:

1. 在/tmp/install 上上传myapp.war"、deploy.sh"
2. chmod +x deploy.sh
3. ./deploy.sh

脚本会处理一切.但我想通过 glassfish http 控制台仅上传一个战争文件并获得相同的结果.

and the script will take care of everything. but i'd like to upload only a war file via glassfish http console and obtain the same result.

有没有办法让一个名为before contextInitialized 的类或脚本?

is there a way to have a class or script called before contextInitialized?

你会如何部署这个东西?

how would you deploy this thing?

为了完整起见，这里有一些附加信息:

for completeness here are some additional info:

虽然 glassfish 理解/myapp/.../persistence.xml(有时也执行 CREATE SCHEMA myapp，有时不是，显然是随机的 - 但它很好)，

while glassfish understands /myapp/.../persistence.xml (sometimes executing also CREATE SCHEMA myapp, sometimes not, apparently random - but it's fine),

我绝对不能让 glassfish 读取/myapp/WEB-INF/glassfish-resources.xml.它忽略这个文件.

i definitely can't make glassfish read /myapp/WEB-INF/glassfish-resources.xml. it ignores this file.

更新glassfish 读取文件，但在 jndi 名称前加上 java:app/ 会破坏其他引用.意识到这件事后，我用前缀重写了引用，现在它工作正常.最后，我注意到如果 glassfish-resources.xml 在 META-INF(而不是 WEB-INF)内， glassfish 会读取文件并且它也存在于 http ui 下的应用程序 > myapp > 描述符"

UPDATE glassfish reads the file but prefixes jndi names with java:app/ breaking other references. being aware of this thing i rewrite references with prefix and now it is working fine. lastly, i noted that if glassfish-resources.xml is inside META-INF (instead of WEB-INF) glassfish reads the file and it is also present in http ui under "applications > myapp > descriptors"

推荐答案

我终于找到了解决方案:

finally i found a solution:

1. 数据库创建/升级:在ServletContextListener.contextInitialized中，如果不存在，我使用编译时生成的ddl脚本创建数据库，或者使用liquibase升级数据库如果存在.不再使用persistence.xml 来生成数据库.

1. database create/upgrade: in ServletContextListener.contextInitialized i use compile-time-generated ddl script to create database if not exists, or use liquibase to upgrade database if exists. no more persistence.xml usage for database generation.

身份验证领域部署:我不部署或创建任何特定于容器的领域.在 ServletContextListener.contextInitialized 中，我注册了一个自定义的 JASPIC 实现，它本身就是一个 JAAS 登录模块包装器.感谢@ArjanTijms 提供这篇文章和这个答案

authentication realm deploy: i don't deploy or create any container-specific realm. in ServletContextListener.contextInitialized i register a custom JASPIC implementation, which is itself a JAAS login module wrapper. thanks to @ArjanTijms for this aricle and this answer
