Spring Boot @ComponentScan exclude 不起作用

Spring Boot About 723 words

现象

使用了@ComponentScanexcludeFilters但不起作用。

示例代码

@ComponentScan(excludeFilters = @Filter(type = FilterType.ASSIGNABLE_TYPE, classes = TestComponent.class))
@SpringBootApplication
public class App {
    public static void main(String[] args) {
        SpringApplication.run(App.class, args);
    }
}

原因

有其他@Configuration使用@Bean注入了该对象。

解决

使用@SpringBootApplicationexclude属性,移除注入的@Bean对象。

@ComponentScan(excludeFilters = @Filter(type = FilterType.ASSIGNABLE_TYPE, classes = TestComponent.class))
@SpringBootApplication(exclude = TestConfig.class)
public class App {
    public static void main(String[] args) {
        SpringApplication.run(App.class, args);
    }
}
