Spring BeanUtils, cglib BeanCopier, apache BeanUtils PropertyUtils Bean replication performance comparison
Tips before viewing:
The Eclipse version used in this article is Photon Release (4.8.0), and the JDK version is 1.6.0_45.
This article only compares the performance of each Bean replication, the specific analysis will be added in the future.
1. Result analysis
The test uses each method to test 10 times to average, and the time unit is milliseconds.
This analysis result is for reference only. If there is any error, please leave a message to point it out, thank you.
| 10 times | 1000 times | 10000 times | 100000 times | |
|---|---|---|---|---|
| get set | 1 | 1.1 | 3.4 | 22.7 |
| cglib BeanCopier | 0.1 | 0.3 | 4.4 | 9.7 |
| spring BeanUtils | 154.7 | 173 | 236.5 | 281.1 |
| apache PropertyUtils | 138.5 | 196.4 | 271.3 | 499.6 |
| apache BeanUtils | 140.1 | 222 | 385.9 | 789.4 |
In a comprehensive comparison, get set is very efficient within 10,000 times. The overall efficiency of cglib BeanCopier is very high, which is more obvious when the amount of data is larger.
2. Test the code
The copied entities Person.java , PersonDto.java
