修复 Mysql 测试容器初始化脚本中的定界符语法错误

Question

我想用测试容器测试一个存储过程。 因此，我使用包含存储过程定义的 SQL 脚本初始化我的容器，但出现此语法错误

java.lang.IllegalStateException: Failed to load ApplicationContext
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'initializer' defined in com.api.bankApi.services.TransactionServiceTest$TestConfig: Invocation of init method failed; nested exception is org.springframework.data.r2dbc.connectionfactory.init.ScriptStatementFailedException: Failed to execute SQL script statement #7 of class path resource [schema.sql]: DELIMITER $$ CREATE PROCEDURE make_transaction(IN trans_type varchar(45),IN v_amount decimal(17,2),IN trans_id varchar(255) ) exitSub:BEGIN DECLARE EXIT HANDLER for SQLEXCEPTION BEGIN DECLARE errNom INT UNSIGNED DEFAULT 0; nested exception is io.r2dbc.spi.R2dbcBadGrammarException: [1064] [42000] You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'DELIMITER $$ CREATE PROCEDURE make_transaction(IN trans_type varchar(45),IN v_am' at line 1

来自 mysql 文档，分隔符语法似乎是正确的我想知道可能是什么问题

这是初始化代码

@TestConfiguration
    static class TestConfig {
        @Bean
        public ConnectionFactoryInitializer initializer() {
            ConnectionFactoryOptions options = MySQLR2DBCDatabaseContainer.getOptions(database);

            ConnectionFactoryInitializer initializer = new ConnectionFactoryInitializer();
            initializer.setConnectionFactory(ConnectionFactories.get(options));

            CompositeDatabasePopulator populator = new CompositeDatabasePopulator();
            populator.addPopulators(new ResourceDatabasePopulator(new ClassPathResource("schema.sql")));
            populator.addPopulators(new ResourceDatabasePopulator(new ClassPathResource("data.sql")));
            initializer.setDatabasePopulator(populator);

            return initializer;
        }
    }

注意：当我删除存储过程代码时，脚本运行正常。 并且存储过程在我的本地数据库中也运行良好

编辑：

经过研究，我使用了 testcontainers initscript，它现在正在执行而不会中断，但现在似乎所有其他语句都在执行，除了创建存储过程。 因为当我运行测试时，我得到 PROCEDURE does not exist error for tests that execute the procedure。

private static final MySQLContainer database = new MySQLContainer("mysql:8");
    static {
        try {
            final String script = Resources.toString(Resources.getResource("schema.sql"), Charsets.UTF_8);
            database.start();
            ScriptUtils.executeDatabaseScript(new JdbcDatabaseDelegate(database,""), "schema.sql", script, false, false, DEFAULT_COMMENT_PREFIX, 
                    DEFAULT_STATEMENT_SEPARATOR, "$$", "$$$");
        } catch (Exception ex) {
            Logger.getLogger(TransactionServiceTest.class.getName()).log(Level.SEVERE, null, ex);
        }
    }

失败的测试错误

TransactionServiceTest.depositFundsSuccess expectation "assertNext" failed (expected: onNext();
actual:onError(org.springframework.r2dbc.BadSqlGrammarException:

所以最好的办法是将sql文件复制到容器中，在容器初始化时执行/docker-entrypoint-initdb.d。 这是sql团队的推荐。 所以这就是实现它的方法。

 private static final MySQLContainer database = new MySQLContainer("mysql:8");
    static {
        try {
            database.withCopyFileToContainer(MountableFile.forClasspathResource("schema2.sql"), "/docker-entrypoint-initdb.d/schema.sql");
            database.start();
        } catch (Exception e) {
            System.out.println(e.getMessage());
        }       
    }
