What are the most commonly used technology stacks for Java?
Inventory of commonly used technology stacks for Java development
1. Preface
Recently, many people have asked me privately about my commonly used Java development technology stack, so today I will summarize a wave of commonly used Java technology stacks.
2. JDK
Most of the JDK versions have now been moved to 8. Those who use 11 are ahead of the curve. Please look for the LTS version! Do not use 9, 10, 12, 13, and 14 in production. It is recommended to use Open JDK between Oracle JDK and Open JDK to avoid unnecessary commercial disputes. Amazon Corretto and Alibaba Dragonwell are both good. 7 There is no need to consider compatibility issues too much for the above, but it is best to test before migrating.
2. Web framework
The mainstream is still the Spring MVC of the Servlet series. Structs should only be used in old projects. The responsive framework Spring Webflux has begun to come into view, and more and more people are trying it and asking questions. It is recommended that students who are interested in seizing the future direction learn about it.
3. Web container
Currently Tomcat should still be the most popular, but in recent years Red Hat’s Undertow has also become popular. Jetty has no advantage in actual production and may be used for testing. Competent companies will choose Netty to implement high-performance web containers on their own.
4. ORM framework
Now Mybatis is still the leader in China, but there are few related tutorials abroad. Next is the JPA system, which mainly includes Spring Data JPA and Hibernate. If you are interested, you can check out JOOQ. With the rise of reactive programming, JDBC has begun to have potential rivals R2DBC, and you need to continue to pay attention to the trends.
5. Spring
When it comes to Java being inseparable from Spring, the dominance of the Spring ecosystem remains unshakable. At present, single applications are still dominated by Spring Boot, and the microservice Spring Cloud system still has the absolute advantage. But is your project really suitable for microservices? Spring has begun to turn to responsiveness in recent years. Webflux, R2DBC, and more recently RSocket are some of the responsive frameworks or protocols officially promoted by Spring. So responsiveness must be included in your knowledge list.
6. Database
Most of them are Mysql, but MSSQL and PostgreSQL are also used a lot. The development of the domestic cloud-native database TiDB cannot be underestimated. Although Mongo, a document database, has had some security issues in the past two years, it still leads the field. The in-memory database Redis still occupies an important position in the field of caching, and Memcached and Hazelcast also often appear in the field of vision.
7. Search engine
In the field of search engines, Lucene and its two derivatives, Solr and ElasticSearch, have an absolute advantage, and ElasticSearch is more active.
8. Back-end template engine
Today, when the separation of front-end and back-end has become popular, the living space of template engines has once again been compressed. Currently, I use them most for code generators. They are rarely used anymore, and Freemarker and Velocity Thymeleaf are mentioned less and less.
9. Workflow
The most commonly used and well-known ones are Activity and Flowable.
10. Other language-independent middleware
Message queues are mainly Kafka, RocketMQ, and RabbitMQ. The old ActiveMQ is beginning to decline. I don’t know why Pulsar, which Yahoo donated to Apache, is not as popular as zookeeper. . Nginx is still the first choice for high-performance web servers and proxy servers.
These are some of my views and opinions on the current commonly used technology stacks in Java.

VSCode settings.json location
Aug 01, 2025 am 06:12 AM
The settings.json file is located in the user-level or workspace-level path and is used to customize VSCode settings. 1. User-level path: Windows is C:\Users\\AppData\Roaming\Code\User\settings.json, macOS is /Users//Library/ApplicationSupport/Code/User/settings.json, Linux is /home//.config/Code/User/settings.json; 2.

How to handle transactions in Java with JDBC?
Aug 02, 2025 pm 12:29 PM
To correctly handle JDBC transactions, you must first turn off the automatic commit mode, then perform multiple operations, and finally commit or rollback according to the results; 1. Call conn.setAutoCommit(false) to start the transaction; 2. Execute multiple SQL operations, such as INSERT and UPDATE; 3. Call conn.commit() if all operations are successful, and call conn.rollback() if an exception occurs to ensure data consistency; at the same time, try-with-resources should be used to manage resources, properly handle exceptions and close connections to avoid connection leakage; in addition, it is recommended to use connection pools and set save points to achieve partial rollback, and keep transactions as short as possible to improve performance.
python itertools combinations example
Jul 31, 2025 am 09:53 AM
itertools.combinations is used to generate all non-repetitive combinations (order irrelevant) that selects a specified number of elements from the iterable object. Its usage includes: 1. Select 2 element combinations from the list, such as ('A','B'), ('A','C'), etc., to avoid repeated order; 2. Take 3 character combinations of strings, such as "abc" and "abd", which are suitable for subsequence generation; 3. Find the combinations where the sum of two numbers is equal to the target value, such as 1 5=6, simplify the double loop logic; the difference between combinations and arrangement lies in whether the order is important, combinations regard AB and BA as the same, while permutations are regarded as different;

python pytest fixture example
Jul 31, 2025 am 09:35 AM
fixture is a function used to provide preset environment or data for tests. 1. Use the @pytest.fixture decorator to define fixture; 2. Inject fixture in parameter form in the test function; 3. Execute setup before yield, and then teardown; 4. Control scope through scope parameters, such as function, module, etc.; 5. Place the shared fixture in conftest.py to achieve cross-file sharing, thereby improving the maintainability and reusability of tests.

How to work with Calendar in Java?
Aug 02, 2025 am 02:38 AM
Use classes in the java.time package to replace the old Date and Calendar classes; 2. Get the current date and time through LocalDate, LocalDateTime and LocalTime; 3. Create a specific date and time using the of() method; 4. Use the plus/minus method to immutably increase and decrease the time; 5. Use ZonedDateTime and ZoneId to process the time zone; 6. Format and parse date strings through DateTimeFormatter; 7. Use Instant to be compatible with the old date types when necessary; date processing in modern Java should give priority to using java.timeAPI, which provides clear, immutable and linear
Troubleshooting Common Java `OutOfMemoryError` Scenarios
Jul 31, 2025 am 09:07 AM
java.lang.OutOfMemoryError: Javaheapspace indicates insufficient heap memory, and needs to check the processing of large objects, memory leaks and heap settings, and locate and optimize the code through the heap dump analysis tool; 2. Metaspace errors are common in dynamic class generation or hot deployment due to excessive class metadata, and MaxMetaspaceSize should be restricted and class loading should be optimized; 3. Unabletocreatenewnativethread due to exhausting system thread resources, it is necessary to check the number of threads, use thread pools, and adjust the stack size; 4. GCoverheadlimitexceeded means that GC is frequent but has less recycling, and GC logs should be analyzed and optimized.
