列出SpringApplication.run加载的所有bean

Question

我正在尝试在启动SpringApplication时登记我编写的所有bean。

获取所有列出的bean已完成。这段代码做到了。

String[] beanNames = appContext.getBeanDefinitionNames();

Arrays.sort(beanNames);
for (String beanName : beanNames) {
        System.out.println(beanName);
}

我尝试使用基本过滤器来查找我的东西。

String[] beanNames = appContext.getBeanDefinitionNames();

Arrays.sort(beanNames);
for (String beanName : beanNames) {
    if (beanName.matches("(.*)Controller"))
        System.out.println(beanName);
}

但这不起作用，因为当加载类时，它实际上是加载的bean名称而不是类的确切名称。因此，如果我写了一个 my.personal.package.structure.MyController ，它很可能会显示为 myController 。包结构信息丢失，呈现这种技术，并不十分有效。

有没有人尝试过其他有效的方法。我希望这对于开发人员进行调试非常方便。

使用@Autowired ConfigurableApplicationContext context; ..... ConfigurableListableBeanFactory beansFactory = context.getBeanFactory(); String[] beansNames = beansFactory.getBeanDefinitionNames(); Set<String> beansType = new HashSet<>(); for(String beanName : beansNames){ if (beanName.matches("(.*)Controller")){ beansType.add(beansFactory.getType(beanName).toString()); } } 可以获得所有bean类型。例如：

Spring boot actuator

显示所有bean的其他更简单的选项是 在您使用spring-web的情况下您可以使用pom.xml。在/bean中添加下一个dependency，然后转到#include <iostream> using namespace std; int getSmallest(int first, int second, int third, int fourth, int fifth); int getLargest(int first, int second, int third, int fourth, int fifth); double calculateAverage(int largest, int smallest, int sum); int main() { int first, second, third, fourth, fifth; int smallest, largest, sum; //double ave; //read input of 5 scores from judges cin >> first; cin >> second; cin >> third; cin >> fourth; cin >> fifth; smallest = getSmallest ( first, second, third, fourth, fifth ); largest = getLargest ( first, second, third, fourth, fifth ); sum = (first + second + third + fourth + fifth); //ave = calculateAverage(largest, smallest, sum); //cout << ave << endl; cout << "The average is " << (double)calculateAverage(largest, smallest, sum) << endl; return 0; } int getSmallest(int first, int second, int third, int fourth, int fifth) { int smallest = 0; if ( first <= smallest ) { smallest = first; } if ( second <= smallest ) { smallest = second; } if ( third <= smallest ) { smallest = third; } if ( fourth <= smallest ) { smallest = fourth; } if ( fifth <= smallest ) { smallest = fifth; } return smallest; } int getLargest(int first, int second, int third, int fourth, int fifth) { int largest = 0; if ( first >= largest ) { largest = first; } if ( second >= largest ) { largest = second; } if ( third >= largest ) { largest = third; } if ( fourth >= largest ) { largest = fourth; } if ( fifth >= largest ) { largest = fifth; } return largest; } double calculateAverage(int largest, int smallest, int sum) { return (((double)sum) - ((double)largest + (double)smallest)) / 3.0; } 端点以显示所有bean，它将显示bean的名称和类。
