Spring Boot is an open-source Java-based framework used to create stand-alone, production-grade Spring-based applications. It is built on top of the Spring Framework and simplifies the process o...
MyBatis and Hibernate are both popular frameworks for data persistence in Java applications, but they serve different purposes and have different strengths. Whether one is considered "better" than the other often depends...
In MyBatis, the @MapKey annotation is used in conjunction with the @Results annotation to specify how the results of a query should be mapped to a Map instead of a list or a single object. This is particularly usef...
Lazy loading is a design pattern commonly used in programming to defer the initialization of an object until the point at which it is needed. In the context of MyBatis, a popular persistence framework in Java, lazy loadi...
In MyBatis, the CacheRef tag is used to define a reference to another cache configuration. This is particularly useful when you want to share the same cache across multiple mappers or SQL statements. By using `CacheRef...
In MyBatis, environment properties are used to configure the settings for the database connection and other related resources. These properties are typically defined in the MyBatis configuration file (usually `mybatis-co...
Handling large queries in MyBatis effectively requires a combination of strategies to ensure performance, maintainability, and resource management. Here are some best practices: Pagination: Use Pagination*...
In MyBatis, the default fetch size when executing queries is typically set to 0. This means that the driver will use its default fetch size, which can vary depending on the database and JDBC driver being used. If you...
In MyBatis, tags are used to define various elements of SQL mapping and configuration in XML files. They help structure the SQL statements, parameter mappings, result mappings, and other configurations in a clear and org...
Using multiple parameters instead of a single parameter in a statement depends on several factors, including clarity, flexibility, and the specific requirements of the situation. Here are some guidelines to help you deci...
In MyBatis, if the value of a parameter does not match the target type specified in the parameterType attribute, several things can happen depending on the context and the nature of the mismatch: Type Conversion*...
Yes, it is definitely possible to integrate Spring Boot with MyBatis. MyBatis is a persistence framework that simplifies the interaction with databases by allowing you to use SQL directly in your code while providing a m...
Certainly! MyBatis is a popular persistence framework in Java that allows you to work with SQL databases using XML or annotations. One of its powerful features is the ability to use dynamic SQL statements, which can be p...
Certainly! In MyBatis, a custom type handler allows you to define how to map a specific Java type to a database type and vice versa. This is particularly useful when you have a Java type that doesn't have a direct mappin...
In MyBatis, result maps are used to define how the results of a SQL query are mapped to Java objects. There are several types of result maps available in MyBatis, each serving different purposes. Here are the main types:...
In MyBatis, both @Select and @Results annotations are used to define SQL queries and map the results to Java objects, but they serve different purposes. Purpose: The @Select annotation is used ...
SQL mappers in MyBatis are a key feature that allows developers to map SQL statements to Java methods, facilitating the interaction between Java applications and relational databases. MyBatis is a persistence framework t...
Configuring a data source for MyBatis involves several steps, including setting up the MyBatis configuration file, defining the data source properties, and integrating it with your application. Below are the steps to con...
MyBatis is a popular persistence framework that offers several advantages over using plain JDBC (Java Database Connectivity) for database interactions. Here are some of the key benefits of using MyBatis: Simplified...
MyBatis is a popular persistence framework in Java that simplifies the interaction between applications and databases. It allows developers to work with SQL directly while providing a mapping layer to convert between Jav...
MyBatis is a popular open-source persistence framework in Java that simplifies the interaction between Java applications and relational databases. It provides a way to map Java objects to database records and vice versa,...
Declarative exception handling in Struts refers to a mechanism that allows developers to manage exceptions in a centralized and declarative manner, rather than handling them programmatically within the action classes. Th...
Client-side validation in a JSP (JavaServer Pages) form can be enabled using JavaScript. This allows you to validate user input before it is sent to the server, improving user experience and reducing server load. Here’s ...
In the context of the Struts framework, OGNL (Object-Graph Navigation Language) and ValueStack are important concepts that facilitate the handling of data and expressions in web applications.
