Gradle multi-project construction and its dependency analysis problem and solutions

This article discusses in-depth the problem that in Gradle multi-project construction, subprojects cannot parse external libraries introduced by another subproject that they depend on. By analyzing the essential differences between Gradle implementation and API dependency configuration, two core solutions are provided: one is to configure the dependencies that need to be exposed to the outside in the shared module as API type to achieve transitive exposure; the other is to explicitly declare the required dependencies in the consumer module directly. The article aims to help developers understand and effectively solve dependency management challenges in multi-project environments and ensure smooth construction processes.

How to avoid deadlocks in Java

Deadlock occurs in Java when multiple threads are waiting for resources held by each other and block permanently, the following 6 methods can be effectively prevented: 1. Always acquire the lock in a consistent order to avoid loop waiting; 2. Use tryLock() with timeout to make the thread actively give up when it cannot acquire the lock; 3. Minimize the range and holding time of the lock to avoid time-consuming operations in the synchronous block; 4. Try to avoid nested locks and use the thread-safe class or message delivery mechanism in java.util.concurrent; 5. Make method calls outside the synchronous block (open call) to prevent indirectly leading to lock competition; 6. Use thread dumps, JVM analysis tools and static inspection tools to detect potential deadlocks. By rationally designing lock strategies and reducing concurrency

How to replace a string after a specific string in Java

This article describes how to elegantly replace strings after specific words in text in Java. By using the replaceFirst method and simple regular expressions, we can easily achieve this, avoiding writing verbose and complex code. This article will provide clear code examples and notes to help you master this trick quickly.

How to convert an array to an ArrayList in Java

Use Arrays.asList() combined with ArrayList constructor to convert an object array into a mutable ArrayList; 2. For basic arrays such as int[], it is necessary to convert through manual loops or Java8's Arrays.stream().boxed().collect(); 3. Use streams to also implement filtering and mapping operations during conversion. You should select the appropriate method based on the array type and whether you need to modify the list, and finally get a dynamically adjustable ArrayList object.

Java selection sorting: step by step display of algorithm execution process

This tutorial explains in detail how to implement the selection sorting algorithm in Java, and highlights how to modify existing code to print the current state of the array after each iteration is completed. By adding print statements to the main sort loop, users can clearly track each step of the algorithm to better understand how the selection sort works.

Search strategy for custom object properties in Java ArrayList

This tutorial explores in-depth strategies for finding specific properties (such as names) in Java ArrayList based on custom objects (such as Product). It explains why this function cannot be achieved directly using ArrayList.contains(String) and provides three effective implementation solutions: direct search based on loop iteration, functional search using the Java 8 Stream API, and efficient and fast search methods by building HashMap, aiming to help developers choose the most suitable search mechanism for their scenarios.

Optimization and transaction management practice of Sybase stored procedures and unique IDs

This article discusses the problem of duplication when stored procedures generate incremental IDs in Sybase databases, even if the application layer has configured the SERIALIZABLE isolation level. The core reason lies in the non-atomicity of internal operations of stored procedures and the lack of transaction management. The article provides two stored procedure optimization solutions: introducing explicit transactions to ensure atomicity, or implementing more efficient atomic operations through a single UPDATE statement, and emphasizes the importance of database locking mechanisms (such as datarows) to concurrency performance and data integrity, aiming to guide developers to build robust ID generation mechanisms.

How to get and set field values using reflection in Java

Use getField() to get public fields, getDeclaredField() to get all fields including private fields; 2. Access private fields through setAccessible(true); 3. Call get() and set() methods to read or modify the field values, and pass null into static fields as object parameters; 4. NoSuchFieldException and IllegalAccessException exceptions must be handled; 5. The reflection function is powerful but affects performance and destroys encapsulation, and should be used with caution in scenarios such as frameworks and serialization.

Jackson handles Double type fields in String/pure numeric format

This article aims to solve the problem that Jackson may encounter when mapping String or purely digital format data to Double type fields during deserialization. By unifying the Jackson dependency version, you can ensure that it can handle both formats correctly, avoiding the NoSuchFieldError: USE_FAST_DOUBLE_PARSER error. This article will explain the root cause of the problem and how to resolve it through version management.
