How to simplify field mapping issues in system docking using MapStruct?

Efficiently handle field mapping problems in system docking
System integration often faces the challenge of field mapping: field names and types are inconsistent between different systems, resulting in cumbersome manual mapping. For example, field naming differences, data type conversion (such as string date to Date type), field mismatch (one field maps to multiple fields), structure differences (parallel structures and nested structures) and other problems all increase development difficulty and error risk. The traditional manual set / get method is time-consuming and error-prone.
MapStruct provides an elegant solution to this puzzle. It is a Java annotation processor that automatically generates type-safe Bean mapping code, significantly improving efficiency and reducing error rates.
The advantages of MapStruct are:
-
Convenient field mapping configuration: Use
@Mappingannotation to easily configure the correspondence between source and target fields, and can quickly map even if the field names are different. For example:@Mapper public interface MyMapper { @Mapping(source = "aFieldName", target = "bFieldName") BSystemDTO map(ASystemDTO aSystemDTO); } -
Flexible custom type conversion: Custom conversion methods can be defined for fields that require type conversion. For example, convert a string date to
Datetype:@Mapper public interface MyMapper { @Mapping(source = "stringDate", target = "date", qualifiedByName = "stringToDate") BSystemDTO map(ASystemDTO aSystemDTO); @Named("stringToDate") default Date stringToDate(String stringDate) { // Date conversion logic... return java.sql.Date.valueOf(stringDate); //Example} } Elegantly handle field count and structural differences: MapStruct supports mapping one field to multiple fields and handling complex structural differences between different systems (for example, mapping flat structures to nested structures).
Through MapStruct, you only need to write a concise mapping configuration file or annotation class to automatically generate efficient and reliable mapping code, greatly simplifying the system docking process and improving development efficiency.

AMD announces 'Sinkclose' high-severity vulnerability, affecting millions of Ryzen and EPYC processors
Aug 10, 2024 pm 10:31 PM
According to news from this site on August 10, AMD officially confirmed that some EPYC and Ryzen processors have a new vulnerability called "Sinkclose" with the code "CVE-2023-31315", which may involve millions of AMD users around the world. So, what is Sinkclose? According to a report by WIRED, the vulnerability allows intruders to run malicious code in "System Management Mode (SMM)." Allegedly, intruders can use a type of malware called a bootkit to take control of the other party's system, and this malware cannot be detected by anti-virus software. Note from this site: System Management Mode (SMM) is a special CPU working mode designed to achieve advanced power management and operating system independent functions.
The difference between multithreading and asynchronous c#
Apr 03, 2025 pm 02:57 PM
The difference between multithreading and asynchronous is that multithreading executes multiple threads at the same time, while asynchronously performs operations without blocking the current thread. Multithreading is used for compute-intensive tasks, while asynchronously is used for user interaction. The advantage of multi-threading is to improve computing performance, while the advantage of asynchronous is to not block UI threads. Choosing multithreading or asynchronous depends on the nature of the task: Computation-intensive tasks use multithreading, tasks that interact with external resources and need to keep UI responsiveness use asynchronous.
Intel Core Ultra 9 285K processor exposed: single-core running score is 4% faster than Ryzen 9 9950X and multi-core is 14% faster
Aug 21, 2024 pm 04:46 PM
According to news from this website on August 21, technology media WccFtech reported today that the Intel Core Ultra9285K "ArrowLake" processor appeared in the GeekBench6 benchmark library, surpassing the Core i9-14900KS and Ryzen99950X processors. Test platform The test platform exposed this time is ASUS ROGSTRIXZ890-AGamingWIFI motherboard and 64GBDDR5-6400 memory. Introduction to the Intel Core Ultra9285K "ArrowLake-S" desktop processor. The PL1 power consumption of the Intel Core Ultra9285K processor is 125W and it uses a 7nm process (CPU-Z information, it should actually use UK
Free choice of power consumption? Sources claim AMD will unlock 105W TDP configuration for R5 9600X and R7 9700X via AGESA 1.2.0.1a update
Aug 15, 2024 am 07:38 AM
According to news from this site on August 14, two of the AMD Ryzen 9000 series desktop processors (R59600X and R79700X) were officially launched on August 8, priced at 1,949 yuan and 2,549 yuan respectively. Although the TDP of these two processors has been significantly reduced (65W) and the initial price has also been reduced, compared with the previous generation Ryzen 7000 series, the performance has only been improved by about 10% or even single-digit percentages. This is for some users who are more performance-oriented. It may be difficult for players to accept it. Considering this situation, it may be a good solution to let players decide the level of performance release. @g01d3nm4ng0 said that AMD will pass the AGESA1.2.0.1aPatchA microcode patch to Ryzen

What is c# multithreading programming? C# multithreading programming uses c# multithreading programming
Apr 03, 2025 pm 02:45 PM
C# multi-threaded programming is a technology that allows programs to perform multiple tasks simultaneously. It can improve program efficiency by improving performance, improving responsiveness and implementing parallel processing. While the Thread class provides a way to create threads directly, advanced tools such as Task and async/await can provide safer asynchronous operations and a cleaner code structure. Common challenges in multithreaded programming include deadlocks, race conditions, and resource leakage, which require careful design of threading models and the use of appropriate synchronization mechanisms to avoid these problems.
