解决方案
注意:您为 Spring 和 Lombok 配置了 OSS bean.
关于 Lombok，您在类级别声明 @Builder 可能因此生成构造函数.
问题是，从 Spring 4 开始，默认情况下，声明构造函数的 Spring 组件会自动被视为自动装配的构造函数.
而您遇到的异常.
看到你实例化OSS实例的方式:
oss = OSS.builder().name("Dinesh").version("1.0").license("apache 2.0").usage("dynamic").comment("approved").构建()；OSS 不必配置 Spring bean，但必须是手头创建的普通对象.
你不想创建这个对象的单个实例，你想根据客户端请求实例化它，最后你也不希望在客户端之间共享它.
所以只要去掉这个类的@Component注解即可.

Description:
Parameter 0 of constructor in com.din.OSS required a bean of type 'java.lang.String' that could not be found.
Action:
Consider defining a bean of type 'java.lang.String' in your configuration.
There are 3 classes under package
BduckApp1Application .java
package com.din;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class BduckApp1Application {
public static void main(String[] args) {
SpringApplication.run(BduckApp1Application.class, args);
}
}

public String comment;
}
pom.
<?I tried all the solution that is mentioned for the similar error in the various stackoverflow post. All suggests, to move the classes to the same folder as @SpringBootApplication class or include the package with the attribute of it basepackage. None worked for me. Any help would be great!
解决方案
Beware : you configured your OSS bean both for Spring and Lombok.
And about Lombok you declared at the class level @Builder that probably has as consequence to generate a constructor.
And the problem is that from Spring 4,by default, a Spring component that declares a constructor is automatically considered as an autowired constructor.
Whereas the exception you encounter.
Seeing the way you instantiated the OSS instance :
oss = OSS.builder().name("Dinesh").version("1.0").license("apache 2.0").usage("dynamic").comment("approved").build();
the OSS doesn't have to be configured a Spring bean but have to be a plain object created at hand.
You don't want to create a single instance of this object, you want instantiate it according to the client request and at last you don't want share it between clients either.
So just remove the @Component annotation of this class.
这篇关于com.din.OSS 中构造函数的参数 0 需要一个无法找到的“java.lang.String"类型的 bean的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
