1. 应用程序依赖项缺失或未正确安装:
日志示例:
```
2021-01-01 10:00:00 ERROR [main] org.springframework.boot.SpringApplication - Application run failed
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'controller': Unsatisfied dependency expressed through field 'service';
nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.example.service.Service' available: expected at least 1 bean which qualifies as autowire candidate.
Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}
```
2. 应用程序配置错误:
日志示例:
```
2021-01-01 10:00:00 ERROR [main] org.springframework.boot.SpringApplication - Application run failed
org.springframework.beans.factory.BeanDefinitionStoreException: Failed to parse configuration class [com.example.Application];
nested exception is org.springframework.context.annotation.ConflictingBeanDefinitionException: Annotation-specified bean name 'customService' for bean class [com.example.service.CustomServiceImpl] conflicts with existing, non-compatible bean definition of same name and class [com.example.service.CustomServiceInterface]]"
```
3. 端口冲突:
日志示例:
```
2021-01-01 10:00:00 ERROR [main] org.springframework.boot.SpringApplication - Application run failed
org.springframework.boot.web.server.PortInUseException: Port 8080 is already in use
```
4. 内存不足:
日志示例:
```
2021-01-01 10:00:00 ERROR [main] org.springframework.boot.SpringApplication - Application run failed
java.lang.OutOfMemoryError: Java heap space
```
这些仅是一些常见的启动失败原因和对应的日志记录示例,在实际应用中,启动失败日志的内容和形式可能根据具体的应用程序和框架而有所不同。查看具体的启动失败日志是确定问题原因的关键。
