Today, I will talk to you about the difference between hibernate and mybatis. Many people may not know much about it. In order to let everyone know more, Xiaobian summarized the following contents for everyone. I hope everyone can gain something according to this article.

Difference between Hibernate and Mybatis

1 Simple introduction to Hibernate framework

Hibernate is an open source object-relational mapping framework, which encapsulates JDBC in a lightweight way and maps objects to database tables. Is a fully automated, fully object-oriented persistence layer framework.

Mybatis framework

Mybatis is an open-source object-relational mapping framework, formerly known as ibatis, which was taken over by Google in 2010. Is a semi-automated persistence layer framework.

2 Differences between the two 2.1 Development aspects

During project development, in terms of speed: Hibernate development, sql statements have been encapsulated, can be used directly to speed up system development; Mybatis is semi-automated, sql needs to be done manually, slightly cumbersome; However, everything is not absolute. If there are many complex statements for a large and complex system project, choosing hibernate is not a good solution. 2.2 SQL optimization aspects Hibernate automatically generates sql, some statements are more cumbersome, will consume some performance; Mybatis manually write sql, can avoid unnecessary queries, improve system performance;2.3 object management comparison Hibernate is a complete object-relational mapping framework. In development projects, there is no need to pay too much attention to the underlying implementation, as long as you manage objects. Mybatis needs to manage its own mapping;2.4 Cache aspects

Same points:

Hibernate and Mybatis L2 caches, in addition to the default caching mechanism, can completely override caching behavior by implementing your own caching or creating adapters for other third-party caching schemes.

Difference:

Hibernate's L2 cache configuration is detailed in the configuration file generated by SessionFactory, and then configured in the specific table-object mapping.

MyBatis 'secondary cache configuration is detailed in each specific table-object mapping, so that different caching mechanisms can be customized for different tables. And Mybatis can share the same cache configuration and instances in namespaces, via Cache-ref.

Compare:

Hibernate has a good management mechanism, users do not need to pay attention to SQL, if the secondary cache dirty data, the system will save; Mybatis should be used carefully to avoid caching CAche.

Hibernate Advantage

Hibernate's DAO layer is simpler to develop than MyBatis, which requires maintenance of SQL and result mappings.

Hibernate is better at object maintenance and caching than MyBatis, and it is easier to maintain objects that are added, deleted, and searched.

Hibernate database portability is very good, MyBatis database portability is not good, different databases need to write different SQL.

Hibernate has a better second-level caching mechanism and can use third-party caching. MyBatis itself provides a poor caching mechanism.

Mybatis Advantage

MyBatis allows for more granular SQL optimization and reduces the number of query fields.

MyBatis is easy to master, while Hibernate has a higher threshold.

Mybatis: compact, convenient, efficient, simple, straightforward, semi-automated

Hibernate: powerful, convenient, efficient, complex, indirect, fully automated

After reading the above, do you have any further understanding of the difference between hibernate and mybatis? If you still want to know more knowledge or related content, please pay attention to the industry information channel, thank you for your support.
