How to solve the problem of TypeAlias loading Mybatis based on SpringBoot
SpringBoot loads Mybatis' TypeAlias
After springboot is compiled into a jar and then run on Linux, it will report that the entity class corresponding to type alias cannot be found. This is a problem with springboot's package scanning.
The project uses Mybatis's DefaultVFS for scanning by default, but in the springboot environment, Mybatis's DefaultVFS will cause problems when scanning packages, so the VFS can only be modified for clarity
Directly paste the code:
@Bean public SqlSessionFactory sqlSessionFactoryBean() throws Exception { logger.info("load SpringBootVFS"); //DefaultVFS在获取jar上存在问题,使用springboot只能修改 VFS.addImplClass(SpringBootVFS.class); SqlSessionFactoryBean sqlSessionFactoryBean = new SqlSessionFactoryBean(); sqlSessionFactoryBean.setDataSource(dataSource()); PathMatchingResourcePatternResolver resolver = new PathMatchingResourcePatternResolver(); Resource[] resources1 = resolver.getResources("classpath*:/mybatis/*.xml"); Resource[] resources2 = resolver.getResources("classpath*:/mysql/mapper/*.xml"); Resource[] resources = (Resource[]) ArrayUtils.addAll(resources1,resources2); sqlSessionFactoryBean.setMapperLocations(resources); sqlSessionFactoryBean.setTypeAliasesPackage("com.xxx.xx.entity"); return sqlSessionFactoryBean.getObject(); }
When springboot is packaged and started, there is an error that the typeAlias class name of mybatis cannot be found.
The springBoot project runs normally on IDEA but an error occurs after packaging. The error is roughly mybatis parsing the Mapper. xml typeAlias cannot find the XX class
The tag in Mapper:
<select parameterType="XXClass" resultMap="XXMap">
This way of writing has no problem running in IDEA, but there is a problem with packaging.
The correct way of writing:
<select parameterType="cn.test.xxx.XXClass" resultMap="XXMap">
The parameterType in the code must use the full path, otherwise an error will occur.
The above is the detailed content of How to solve the problem of TypeAlias loading Mybatis based on SpringBoot. For more information, please follow other related articles on the PHP Chinese website!

iBatis vs. MyBatis: Which should you choose? Introduction: With the rapid development of the Java language, many persistence frameworks have emerged. iBatis and MyBatis are two popular persistence frameworks, both of which provide a simple and efficient data access solution. This article will introduce the features and advantages of iBatis and MyBatis, and give some specific code examples to help you choose the appropriate framework. Introduction to iBatis: iBatis is an open source persistence framework

Several ways to implement batch deletion statements in MyBatis require specific code examples. In recent years, due to the increasing amount of data, batch operations have become an important part of database operations. In actual development, we often need to delete records in the database in batches. This article will focus on several ways to implement batch delete statements in MyBatis and provide corresponding code examples. Use the foreach tag to implement batch deletion. MyBatis provides the foreach tag, which can easily traverse a set.

Interpretation of MyBatis dynamic SQL tags: Detailed explanation of Set tag usage MyBatis is an excellent persistence layer framework. It provides a wealth of dynamic SQL tags and can flexibly construct database operation statements. Among them, the Set tag is used to generate the SET clause in the UPDATE statement, which is very commonly used in update operations. This article will explain in detail the usage of the Set tag in MyBatis and demonstrate its functionality through specific code examples. What is Set tag Set tag is used in MyBati

JPA and MyBatis: Function and Performance Comparative Analysis Introduction: In Java development, the persistence framework plays a very important role. Common persistence frameworks include JPA (JavaPersistenceAPI) and MyBatis. This article will conduct a comparative analysis of the functions and performance of the two frameworks and provide specific code examples. 1. Function comparison: JPA: JPA is part of JavaEE and provides an object-oriented data persistence solution. It is passed annotation or X

Detailed explanation of how to use MyBatis batch delete statements requires specific code examples. Introduction: MyBatis is an excellent persistence layer framework that provides rich SQL operation functions. In actual project development, we often encounter situations where data needs to be deleted in batches. This article will introduce in detail how to use MyBatis batch delete statements, and attach specific code examples. Usage scenario: When deleting a large amount of data in the database, it is inefficient to execute the delete statements one by one. At this point, you can use the batch deletion function of MyBatis

Detailed explanation of MyBatis first-level cache: How to improve data access efficiency? During the development process, efficient data access has always been one of the focuses of programmers. For persistence layer frameworks like MyBatis, caching is one of the key methods to improve data access efficiency. MyBatis provides two caching mechanisms: first-level cache and second-level cache. The first-level cache is enabled by default. This article will introduce the mechanism of MyBatis first-level cache in detail and provide specific code examples to help readers better understand

MyBatisGenerator is a code generation tool officially provided by MyBatis, which can help developers quickly generate JavaBeans, Mapper interfaces and XML mapping files that conform to the database table structure. In the process of using MyBatisGenerator for code generation, the setting of configuration parameters is crucial. This article will start from the perspective of configuration parameters and deeply explore the functions of MyBatisGenerator.

Analysis of MyBatis' caching mechanism: The difference and application of first-level cache and second-level cache In the MyBatis framework, caching is a very important feature that can effectively improve the performance of database operations. Among them, first-level cache and second-level cache are two commonly used caching mechanisms in MyBatis. This article will analyze the differences and applications of first-level cache and second-level cache in detail, and provide specific code examples to illustrate. 1. Level 1 Cache Level 1 cache is also called local cache. It is enabled by default and cannot be turned off. The first level cache is SqlSes
