This is a Maven dependency for the modbus4j library, version 3.0.3, which is a Java library for the Modbus protocol. It allows Java programs to communicate with Modbus devices over TCP/IP, serial, or RTU connections. The groupId is the organization that publishes the library (in this case, "com.infiniteautomation"), the artifactId is the name of the library ("modbus4j"), and the version is the specific version of the library being used. The dependency tag is used in a Maven project to indicate that the project depends on the specified library.

Caused by: java.lang.NoClassDefFoundError: org/springframework/cloud/commons/ConfigDataMissingEnvironmentPostProcessor
这个错误通常是由于缺少Spring Cloud Commons库中的ConfigDataMissingEnvironmentPostProcessor类导致的。您可以尝试添加以下依赖项来解决此问题:
```
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-commons</artifactId>
<version>3.0.3</version>
</dependency>
```
如果您已经添加了这个依赖项,那么请检查您的依赖项版本是否正确,并尝试清除Maven或Gradle缓存,然后重新构建项目。
spring boot集成knife4j
在Spring Boot中集成Knife4j,你需要进行以下步骤:
1. 引入Knife4j的依赖:
```xml
<!-- 版本 -->
<knife4j.version>3.0.3</knife4j.version>
<dependency>
<groupId>com.github.xiaoymin</groupId>
<artifactId>knife4j-spring-boot-starter</artifactId>
<version>${knife4j.version}</version>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
```
2. 配置Knife4j的基本信息:
在`application.properties`或`application.yml`文件中添加以下配置:
```yaml
# Knife4j配置
knife4j:
enable: true
title: Knife4j接口文档
description: Knife4j接口文档示例
version: 1.0.0
contact:
name: your name
url: your url
email: your email
```
3. 启动应用程序并访问Knife4j接口文档:
启动你的Spring Boot应用程序,然后在浏览器中访问`http://localhost:port/doc.html`,其中`port`是你的应用程序的端口号。你将看到Knife4j的接口文档页面,其中包含你的API接口信息。
注意:以上步骤是基本的集成配置,你可以根据自己的需求进行更多的配置和定制化。
