尝试使用H2作为单元测试的测试数据库。该应用程序工作但无法在src / test / resources中找到schema-h2.sql文件。错误：
ServletContext资源[/schema-h2.sql]由＆quot; spring.datasource.schema＆＃39;定义。不存在
我可以在src / test / resources / application.properties中以这种方式定义它并且它不会抛出任何错误......但是，它似乎是基于我的Entity对象创建表。我可以这样说，因为当schema-h2.sql中的表定义没有时，它会将主键放在那里。配置下面的东西......
文件：/workspace/DatabaseAdapter/src/test/resources/schema-h2.sql
schema-h2.sql的内容：
CREATE TABLE translog
(
objectid numeric(18,0),
translog_type varchar(3),
primary_relation numeric(18,0),
transaction_type int,
ADB_SUBJECT varchar(255),
ADB_SEQUENCE int NOT NULL,
ADB_SET_SEQUENCE int,
ADB_TIMESTAMP datetime,
ADB_OPCODE int NOT NULL,
ADB_UPDATE_ALL int,
ADB_REF_OBJECT varchar(64),
ADB_L_DELIVERY_STATUS char(1),
ADB_L_CMSEQUENCE decimal(28,0),
ADB_TRACKINGID varchar(40)
);
实体：
@Entity
@Table(name="translog")
public class Translog {
@Id
@Column(name="objectid")
private Long objectid;
@Column(name="translog_type")
private String translogType;
@Column(name="primary_relation")

@Column(name="transaction_type")

要求它找到h2设置时的堆栈跟踪：

答案 0 :(得分：0)
我只是想发表一个发现。自从实施Jaiwo99的建议以来，我认为我没有问题。我发现通过更改查询...非常简单：
从translog中选择*
由于我得到了这个结果，我的问题显然不是配置，而是H2对SQL与SQL Server的比较方式。我应该先检查一下： - ）
