Spring：HSQL-无法执行数据库脚本

Question

我想用以下两个脚本运行HSQL，然后测试它，但每次遇到我无法处理的错误。

无法执行数据库脚本;嵌套异常是org.springframework.jdbc.datasource.init.ScriptStatementFailedException：无法在资源类路径资源[data.sql]的第4行执行SQL脚本语句：insert into spittle（spitter_id，spittleText，postingTime）values（2，'尝试之春 '新的表达语言'， '2010-06-11'）

更新 - 其他异常已被抛出：

完整性约束违规：外键无父母; SYS_FK_10108 表：唾沫

这是我的脚本：

schema.sql文件

drop table if exists spittle; 
drop table if exists spitter; 

create table spitter (
    id identity, 
    username varchar(25) not null, 
    password varchar(25) not null, 
    fullname varchar(100) not null, 
    email varchar(50) not null, 
    update_by_email boolean not null 
); 

create table spittle (
    id integer identity primary key, 
    spitter_id integer not null, 
    spittleText varchar(2000) not null, 
    postedTime date not null, 
    foreign key (spitter_id) references spitter(id) 
); 

data.sql

insert into spitter (username, password, fullname, email, update_by_email) values ('habuma', 'password', 'Craig Walls', 'craig@habuma.com', false); 
insert into spitter (username, password, fullname, email, update_by_email) values ('artnames', 'password', 'Art Names', 'artnames@habuma.com', false); 

insert into spittle (spitter_id, spittleText, postedTime) values (1, 'Have you read Spring in Action 3? I hear it is awesome!', '2010-06-09'); 
insert into spittle (spitter_id, spittleText, postedTime) values (2, 'Trying out Spring''s new expression language.', '2010-06-11'); 
insert into spittle (spitter_id, spittleText, postedTime) values (1, 'Who''s going to SpringOne/2GX this year?', '2010-06-19');

单元测试

package com.habuma.spitter.persistence; 

import org.springframework.jdbc.datasource.embedded.EmbeddedDatabase; 
import org.springframework.jdbc.datasource.embedded.EmbeddedDatabaseBuilder; 

public class DataAccessUnitTestTemplate { 
    private static EmbeddedDatabase db; 

    @Before 
    public void setUp() { 
     // creates a HSQL in-memory db populated from default scripts classpath:schema.sql and classpath:test-data.sql 
     // obviously, this is the 'in-code' method, but the xml should work for Spring managed tests. 
     db = new EmbeddedDatabaseBuilder().addDefaultScripts().build();  
    } 

    @Test 
    public void testDataAccess() { 
     JdbcSpitterDao jdbc = new JdbcSpitterDao(db); 

     System.out.println(jdbc.getSpitterById(1L)); 

    } 

    @After 
    public void tearDown() { 
     db.shutdown(); 
    } 


} 

Answer 1

你的脚本从0开始的ID列值可以指定起始值。

create table spitter (
    id int generated by default as identity (start with 1) primary key, 
    username varchar(25) not null, 
    password varchar(25) not null, 
    fullname varchar(100) not null, 
    email varchar(50) not null, 
    update_by_email boolean not null 
); 

或者，你可以明确地插入IDS：

insert into spitter (id, username, password, fullname, email, update_by_email) values (1, 'habuma', 'password', 'Craig Walls', 'craig@habuma.com', false);
