在进行DAO本地测试或者单元测试时,db环境有时很难弄,而且即使调通了db环境,有时也不想往db里面灌些无用数据,所以,为了不对真实db环境造成侵入,spring提供了一套虚拟db环境,,利用它可以方便地进行单元测试。
在spring环境中配置:
type支持HSQL、H2、Derby三种。默认为HSQL
schema.sql文件为建库建表语句,data.sql为表数据文件,初始可以先insert一些数据。
配置embedded database之后,就可以将其注入到需要dataSource的DAO中,之后就可以进行DAO单元测试了。
另外,还有一种代码方式来创建embedded database:
EmbeddedDatabaseBuilder builder = new EmbeddedDatabaseBuilder();
EmbeddedDatabase db = builder.type(H2).script("schema.sql").script("test-data.sql").build();
// do stuff against the db (EmbeddedDatabase extends javax.sql.DataSource)
db.shutdown();

I hope this topic can inspire you to understand and utilize the infinite possibilities of Spring+AI more deeply. The Spring framework has a history of more than 20 years in the field of software development, and it has been 10 years since the Spring Boot 1.0 version was released. Now, no one can dispute that Spring

Go language is an efficient, concise and easy-to-learn programming language. It is favored by developers because of its advantages in concurrent programming and network programming. In actual development, database operations are an indispensable part. This article will introduce how to use Go language to implement database addition, deletion, modification and query operations. In Go language, we usually use third-party libraries to operate databases, such as commonly used sql packages, gorm, etc. Here we take the sql package as an example to introduce how to implement the addition, deletion, modification and query operations of the database. Assume we are using a MySQL database.

JUnit is a widely used Java unit testing framework in Spring projects and can be applied by following steps: Add JUnit dependency: org.junit.jupiterjunit-jupiter5.8.1test Write test cases: Use @ExtendWith(SpringExtension.class) to enable extension, use @Autowired inject beans, use @BeforeEach and @AfterEach to prepare and clean, and mark test methods with @Test.

How to use MySQLi to establish a database connection in PHP: Include MySQLi extension (require_once) Create connection function (functionconnect_to_db) Call connection function ($conn=connect_to_db()) Execute query ($result=$conn->query()) Close connection ( $conn->close())

Hibernate polymorphic mapping can map inherited classes to the database and provides the following mapping types: joined-subclass: Create a separate table for the subclass, including all columns of the parent class. table-per-class: Create a separate table for subclasses, containing only subclass-specific columns. union-subclass: similar to joined-subclass, but the parent class table unions all subclass columns.

Apple's latest releases of iOS18, iPadOS18 and macOS Sequoia systems have added an important feature to the Photos application, designed to help users easily recover photos and videos lost or damaged due to various reasons. The new feature introduces an album called "Recovered" in the Tools section of the Photos app that will automatically appear when a user has pictures or videos on their device that are not part of their photo library. The emergence of the "Recovered" album provides a solution for photos and videos lost due to database corruption, the camera application not saving to the photo library correctly, or a third-party application managing the photo library. Users only need a few simple steps

HTML cannot read the database directly, but it can be achieved through JavaScript and AJAX. The steps include establishing a database connection, sending a query, processing the response, and updating the page. This article provides a practical example of using JavaScript, AJAX and PHP to read data from a MySQL database, showing how to dynamically display query results in an HTML page. This example uses XMLHttpRequest to establish a database connection, send a query and process the response, thereby filling data into page elements and realizing the function of HTML reading the database.

PHP is a back-end programming language widely used in website development. It has powerful database operation functions and is often used to interact with databases such as MySQL. However, due to the complexity of Chinese character encoding, problems often arise when dealing with Chinese garbled characters in the database. This article will introduce the skills and practices of PHP in handling Chinese garbled characters in databases, including common causes of garbled characters, solutions and specific code examples. Common reasons for garbled characters are incorrect database character set settings: the correct character set needs to be selected when creating the database, such as utf8 or u
