java - Liquibase CDI 集成

Question

我正在尝试将 Liquibase 集成到我的应用程序中，并希望它在部署时与 CDI 一起运行。我已按照 http://www.liquibase.org/documentation/cdi.html 中的说明进行操作但没有任何运气。这是我的代码

com.example.dbv.LiquibaeProducer

package com.example.dbv;

import java.sql.SQLException;

import javax.annotation.Resource;
import javax.enterprise.inject.Produces;
import javax.sql.DataSource;

import liquibase.integration.cdi.CDILiquibaseConfig;
import liquibase.integration.cdi.annotations.LiquibaseType;
import liquibase.resource.ClassLoaderResourceAccessor;
import liquibase.resource.ResourceAccessor;

public class LiquibaseProducer {

@Resource(mappedName="jdbc/mysql-ds") 
protected DataSource ds;

@Produces
@LiquibaseType
public CDILiquibaseConfig createConfig() {
    CDILiquibaseConfig config = new CDILiquibaseConfig();
    config.setChangeLog("com/example/dbv/changeLog.sql");

    return config;
}

@Produces
@LiquibaseType
public DataSource createDataSource() throws SQLException {
    return ds;
}

@Produces
@LiquibaseType
public ResourceAccessor create() {
    return new ClassLoaderResourceAccessor(getClass().getClassLoader());
}

}

com.example.dbv.changeLog.sql

--liquibase formatted sql

--changeset ci_ms:1
create table test1 (
    id int primary key,
    name varchar(255)
);
--rollback drop table test1;

当我部署应用程序时，出现以下错误:

Answer 1

这确实是一个 Liquibase 问题。 Liquibase CDI 模块在调用 CDIBootstrap.afterDeploymentValidation() 中的 bean 方法时不符合规范。

在 CDI 容器完成启动之前，您无法调用 CDI bean 方法(或者更准确地说，您可以这样做，但它可能有效(在 WildFly 上)或无效(在 GlassFish 上)。

Liquibase 更新应由 @Singleton @Startup EJB 或 servlet 上下文监听器触发，而不是由 CDI 扩展观察者方法触发。
