可以通过以下步骤使用Python判断Spring Boot使用的端口:
1. 导入必要的模块:
```python
import re
import subprocess
```
2. 使用subprocess模块的Popen函数执行命令`netstat -tlnp`,并将结果转换为字符串:
```python
result = subprocess.Popen(['netstat', '-tlnp'], stdout=subprocess.PIPE)
output = result.communicate()[0].decode('utf-8')
```
3. 使用正则表达式查找Spring Boot使用的端口:
```python
pattern = r'tcp\s+\d+\s+\d+\s+\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}:(\d+)\s+.*java'
match = re.search(pattern, output)
if match:
port = match.group(1)
print('Spring Boot is using port', port)
else:
print('Spring Boot is not running')
```
完整的代码如下所示:
```python
import re
import subprocess
result = subprocess.Popen(['netstat', '-tlnp'], stdout=subprocess.PIPE)
output = result.communicate()[0].decode('utf-8')
pattern = r'tcp\s+\d+\s+\d+\s+\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}:(\d+)\s+.*java'
match = re.search(pattern, output)
if match:
port = match.group(1)
print('Spring Boot is using port', port)
else:
print('Spring Boot is not running')
```
