Liquibase 未针对 Spring Boot/MySQL 应用程序执行

Liquibase not executing for Spring Boot/MySQL app

Spring 在这里引导 1.5.8 和 Java 8。我遵循了所有 Spring Boot & Liquibase 指南,但我似乎无法让 Liquibase 工作。

这里是 link 到 GitHub repo 用于准确重现问题,但这里是独家新闻:

我有以下 MySQL 提前创建的 v8 数据库(在应用程序运行之前):

CREATE DATABASE IF NOT EXISTS troubleshooting_db CHARACTER SET utf8 COLLATE utf8_general_ci;

我有以下 src/main/resources/db/changelog 个文件:

db.changelog-master.yaml:
===
databaseChangeLog:
- include:
  file: db/changelog/1-setup.sql

1-setup.sql:

CREATE TABLE IF NOT EXISTS metric_range_categories (
    metric_range_category_id BIGINT UNSIGNED NOT NULL AUTO_INCREMENT,
    metric_range_category_ref_id VARCHAR(36) NOT NULL,
    metric_range_category_name VARCHAR(250) NOT NULL,
    metric_range_category_label VARCHAR(250) NOT NULL,
    metric_range_category_description VARCHAR(500) NOT NULL,

    CONSTRAINT pk_metric_range_categories PRIMARY KEY (metric_range_category_id),

    INDEX idx_metric_range_categories_metric_range_category_ref_id (metric_range_category_ref_id),
    INDEX idx_metric_range_categories_metric_range_category_label (metric_range_category_label),

    CONSTRAINT uc_metric_range_categories_metric_range_category_ref_id UNIQUE (metric_range_category_ref_id),
    CONSTRAINT uc_metric_range_categories_metric_range_category_name UNIQUE (metric_range_category_name),
    CONSTRAINT uc_metric_range_categories_metric_range_category_label UNIQUE (metric_range_category_label)
);

-- Lots of other CREATE TABLE statements down here...

以及以下 JPA 注释实体:

@Entity
@Table(name = "metric_range_categories")
@AttributeOverrides({
        @AttributeOverride(name = "id", column = @Column(name = "metric_range_category_id")),
        @AttributeOverride(name = "refId", column = @Column(name = "metric_range_category_ref_id")),
        @AttributeOverride(name = "name", column = @Column(name = "metric_range_category_name")),
        @AttributeOverride(name = "label", column = @Column(name = "metric_range_category_label")),
        @AttributeOverride(name = "description", column = @Column(name = "metric_range_category_description"))
})
public class MetricRangeCategory extends BaseLookup {
    public MetricRangeCategory() {
    }

    public MetricRangeCategory(Long id, String refId, String name, String label, String description) {
        super(id, refId, name, label, description);
    }
}

在运行时我得到以下异常:

Caused by: org.hibernate.tool.schema.spi.SchemaManagementException: Schema-validation: missing table [metric_range_categories]
    at org.hibernate.tool.schema.internal.SchemaValidatorImpl.validateTable(SchemaValidatorImpl.java:67)
    at org.hibernate.tool.schema.internal.SchemaValidatorImpl.doValidation(SchemaValidatorImpl.java:50)

    at org.hibernate.jpa.boot.internal.EntityManagerFactoryBuilderImpl.build(EntityManagerFactoryBuilderImpl.java:879)
    ... 29 common frames omitted

因此当它启动时,Liquibase 不会 excute/engage 因此 Hibernate JPA 验证失败,因为它正在寻找不存在的 table (因为 Liquibase 从未介入并完成它的工作!)。关于我要去哪里出错的任何想法?为什么 Liquibase 没有加入?

有 2 个不同的问题in the repo:

  1. application.yml 的位置错误。将它从根移动到 src/main/resources
  2. 嵌套在 属性 中 TroubleshootingConfig.Machine 具有空值,因为未创建此 bean "authInfo" 并且上下文初始化失败。这是 Spring Boot Configuration Binding 工作原理的参考。
