  title: SpringBoot Common
  date: 2025-12-15
---

# 一、框架说明
  本框架基于Spring Boot3框架二次开发，增加了依赖包管理和启动项配置等功能。

# 二、项目结构

|   项目模块    |       模块含义        |              主要功能               |
| :-----------: | :-------------------: | :---------------------------------: |
|   starters    |   SpringBoot 启动项   |  主要包括web、jdbc和log启动项配置   |
| autoconfigure | staters具体启动配置类 | 主要包括web和jdbc具体的启动项配置类 |
| dependencies  |        依赖项         |    主要包括本框架中的依赖包管理     |
|   framework   |       通用配置        | 主要包括web和data的一些通用工具方法 |

# 三、项目说明
## 3.1 common模块
  该模块主要声明项目结构，包括autoconfigure、dependencies、framework、starter-parent和starters等模块。
```xml
<modules>
    <!-- modules表示聚合关系，即common有以下模块 -->
    <module>dependencies</module>
    <module>starters</module>
    <module>framework</module>
    <module>autoconfigure</module>
    <module>starter-parent</module>
</modules>
```

## 3.2 dependencies模块
&emsp;&emsp;该模块为其他模块的父模块，声明了一些常用依赖包及版本，通过`<dependencyManagement>`管理，只声明依赖的版本，并不会实际引入依赖。   
&emsp;&emsp;后续有新增依赖时，需要先在dependencies模块声明版本，然后在相应的starter模块中增加依赖。

## 3.3 framework模块
&emsp;&emsp;该模块主要是一些通用的配置。

### 3.3.1 data
&emsp;&emsp;主要提供了2个数据库实体类的基类。
::: code-group
```java [AbstractIdEntity]
@Getter
@Setter
public abstract class AbstractIdEntity {
    @TableId(value = "id", type = IdType.ASSIGN_ID)
    private Long id;
}
```

```java [AbstractEntity]
@Getter
@Setter
public abstract class AbstractEntity extends AbstractIdEntity {
    @TableField(value = "create_time", fill = FieldFill.INSERT)
    private LocalDateTime createTime;

    @TableField(value = "create_by", fill = FieldFill.INSERT)
    private String createBy;

    @TableField(value = "update_time", fill = FieldFill.INSERT_UPDATE)
    private LocalDateTime updateTime;

    @TableField(value = "update_by", fill = FieldFill.INSERT_UPDATE)
    private String updateBy;
}
```
:::

### 3.3.2 web
&emsp;&emsp;主要提供了自定义异常处理类。
::: code-group
```java [ErrorResponse]
/**
 * 错误响应
 */
public final class ErrorResponse {
    /**
     * 自定义code
     */
    private final String code;

    /**
     * 自定义消息
     */
    private final String message;

    public ErrorResponse(String message) {
        this.code = "Unspecified";
        this.message = message;
    }

    public ErrorResponse(String code, String message) {
        this.code = code;
        this.message = message;
    }

    public String getCode() {
        return code;
    }

    public String getMessage() {
        return message;
    }
}
```

```java [CustomException]
/**
 * 自定义异常类
 */
public class CustomException extends AbstractException {

    public CustomException(String errorMessage) {
        super(errorMessage);
    }

    public CustomException(String code, String errorMessage) {
        super(code, errorMessage);
    }

    public CustomException(String errorMessage, Exception innerException) {
        super(errorMessage, innerException);
    }

    public CustomException(String code, String errorMessage, Exception innerException) {
        super(code, errorMessage, innerException);
    }

}
```

```java [AbstractException]
/**
 * 抽象异常类
 */
public abstract class AbstractException extends RuntimeException {
    protected String code;

    public AbstractException(String errorMessage) {
        super(errorMessage);
    }

    public AbstractException(String code, String errorMessage) {
        super(errorMessage);
        this.code = code;
    }

    public AbstractException(String errorMessage, Exception innerException) {
        super(errorMessage, innerException);
    }

    public AbstractException(String code, String errorMessage, Exception innerException) {
        super(errorMessage, innerException);
        this.code = code;
    }

    public String getCode() {
        return code;
    }

    public void setCode(String code) {
        this.code = code;
    }
}
```
:::

### 3.4 starters模块
&emsp;&emsp;该模块为整个项目的核心模块，在实际项目中，通过引入相应的starter模块，并配合autoconfigure模块中的功能，即可实现快速自动装配。   
&emsp;&emsp;该模块的pom.xml声明的依赖会注入到实际的项目中。   
::: danger
在SringBoot3中，自动配置的路径改成了**main->resources->META-INF->spring->org.springframework.boot.autoconfigure.AutoConfiguration.imports**路径，然后在该文件中声明需要自动执行的类。  
之前的SringBoot2，是在**main->resources->META-INF**目录下新建spring.factories文件。    
:::

#### 3.4.1 stater-jdbc
&emsp;&emsp;该模块主要提供数据库相关的配置功能。  
&emsp;&emsp;目前实现的功能有：
1. 配置MybatisPlus拦截器，添加乐观锁和分页插件。
2. 自定义MybatisPlus ID生成器（雪花ID）。
3. 配置MybatisPlus自动填充字段（create_time、create_by、update_time和update_by）。  

::: code-group
```java [JdbcAutoConfiguration]
/**
 * jdbc自动配置
 */
@Configuration(proxyBeanMethods = false)
@ConditionalOnClass(SqlSessionFactory.class)
@Import({YitterGenerator.class, MybatisMetaObjectHandler.class})
public class JdbcAutoConfiguration {
    /**
     * MybatisPlus拦截器
     * @return 拦截器
     */
    @Bean
    public MybatisPlusInterceptor mybatisPlusInterceptor() {
        MybatisPlusInterceptor interceptor = new MybatisPlusInterceptor();
        // 乐观锁插件
        interceptor.addInnerInterceptor(new OptimisticLockerInnerInterceptor());
        // 分页插件
        interceptor.addInnerInterceptor(new PaginationInnerInterceptor(DbType.MYSQL));
        return interceptor;
    }
}
```

```java [YitterGenerator]
/**
 * 雪花id生成器
 */
public class YitterGenerator implements IdentifierGenerator {

    @Override
    public Number nextId(Object entity) {
        return YitIdHelper.nextId();
    }

}
```

```java [MybatisMetaObjectHandler]
/**
 * Mybatis Plus自动填充
 */
public class MybatisMetaObjectHandler implements MetaObjectHandler {
    @Override
    public void insertFill(MetaObject metaObject) {
        this.strictInsertFill(metaObject, Constants.CREATE_TIME_FLAG, LocalDateTime.class, LocalDateTime.now());
        this.strictInsertFill(metaObject, Constants.UPDATE_TIME_FLAG, LocalDateTime.class, LocalDateTime.now());

        if (StpUtil.isLogin()) {
            this.strictInsertFill(metaObject, Constants.CREATE_BY_FLAG, String.class, StpUtil.getLoginIdAsString());
            this.strictInsertFill(metaObject, Constants.UPDATE_BY_FLAG, String.class, StpUtil.getLoginIdAsString());
        }
    }

    @Override
    public void updateFill(MetaObject metaObject) {
        this.strictUpdateFill(metaObject, Constants.UPDATE_TIME_FLAG, LocalDateTime.class, LocalDateTime.now());

        if (StpUtil.isLogin()) {
            this.strictUpdateFill(metaObject, Constants.UPDATE_BY_FLAG, String.class, StpUtil.getLoginIdAsString());
        }
    }
}
```
:::

&emsp;&emsp;`@ConditionalOnClass(SqlSessionFactory.class)`表示只有存在SqlSessionFactory类时，这个配置类才会生效。即如果没有 MyBatis 相关依赖，这个配置类会被 Spring 完全忽略。   
&emsp;&emsp;`@Import`用于导入其他配置类或组件到当前配置类中。  

#### 3.4.2 starter-web
&emsp;&emsp;该模块主要提供web相关的配置功能。  
&emsp;&emsp;目前实现的功能有：  
1. 注册审计拦截器
2. 注册Sa-Token拦截器
3. 注册安全拦截器
4. 配置CORS跨越
5. 全局异常处理器

::: code-group
```java [ServerAutoConfiguration]
@Configuration()
@Import({DefaultExceptionAdvice.class, AuditBodyAdvice.class, CustomProperties.class})
public class ServerAutoConfiguration implements WebMvcConfigurer {
    @Resource
    private CustomProperties customProperties;

SpringBoot MVC总体执行顺序：
1. 进入Tomcat容器
2. 进入Filter过滤器
3. 进入Servlet容器
4. 进入Interceptor拦截器
5. 进入Controller控制器
6. 进入AOP
:::

::: tip
请求和响应体拦截器  
RequestBodyAdvice, ResponseBodyAdvice主要发生在Controller执行前后：
1. preHandle()：请求处理前
2. beforeBodyRead：请求体反序列化前
3. @RequestBody：Controller方法参数绑定
4. Controller：请求处理
5. beforeBodyWrite()：响应体序列化之前
6. postHandle()：请求处理后
7. 视图渲染
8. afterCompletion()：请求结束
:::

::: tip
审计拦截器 可以实现请求日志打印等功能  
HandlerInterceptor 拦截器执行顺序：
1. preHandle()：请求处理前 按注册顺序依次执行。
2. Controller：请求处理 请求到达Controller并被处理。
3. postHandle()：请求处理后，视图渲染前 按注册顺序逆序执行。
4. afterCompletion()：视图渲染后 按注册顺序逆序执行。

# 四、项目发布

## 4.1 发布到Git中
1. 在Gitee/Github中创建工程，需要在工程中创建一个文件夹，例如repo，后续发布的文件要放在该文件夹下。
2. 在maven的setting.xml中添加server和repository信息
```xml
<servers>
    <server>
        <id>gitee</id>
        <username>Cxx0822</username>
        <password>token</password>
    </server>
</servers>

<profiles>
   	<profile>
        <id>gitee</id>
        <repositories>
            <repository>
                <id>central</id>
                <url>https://maven.aliyun.com/repository/central</url>
                <releases>
                    <enabled>true</enabled>
                </releases>
                <snapshots>
                    <enabled>true</enabled>
                </snapshots>
            </repository>

            <repository>
                <id>gitee</id>
                <url>https://gitee.com/Cxx0822/springboot2-common/raw/master/repo</url>
            </repository>
        </repositories>

        <pluginRepositories>
            <pluginRepository>
                <id>central</id>
                <url>https://maven.aliyun.com/repository/central</url>
                <releases>
                    <enabled>true</enabled>
                </releases>
                <snapshots>
                    <enabled>true</enabled>
                </snapshots>
            </pluginRepository>
        </pluginRepositories>
    </profile>
</profiles>

<activeProfiles>
    <activeProfile>gitee</activeProfile>
</activeProfiles>
```

&emsp;&emsp;注：这里要去掉mirror的阿里云镜像。

3. 在工程的根目录的pom.xml中添加发布配置：
```xml
<distributionManagement>
    <repository>
        <id>gitee</id>
        <name>springboot2-common</name>
        <url>file:D:/temp/maven</url>
    </repository>
</distributionManagement>
```

&emsp;&emsp;注：gitee不支持通过deploy发布jar包，可以先发布到本地，再将文件复制到项目文件夹下，通过git push推送。

4. 将本地产生的发布文件上传至git仓库中。
5. 其他项目引用：
```xml
<dependency>
    <groupId>com.cxx</groupId>
    <artifactId>starter-web</artifactId>
    <version>1.0.0</version>
</dependency>
<dependency>
    <groupId>com.cxx</groupId>
    <artifactId>starter-jdbc</artifactId>
    <version>1.0.0</version>
</dependency>
<dependency>
    <groupId>com.cxx</groupId>
    <artifactId>starter-logging</artifactId>
    <version>1.0.0</version>
</dependency>
```

# 五、项目使用
1. 将父工程改为starter-parent模块
```xml
 <parent>
    <groupId>com.cxx</groupId>
    <artifactId>starter-parent</artifactId>
    <version>2.0.0</version>
    <relativePath/>
</parent>
```
2. 根据需要引入starter-web、starter-jdbc和starter-logging模块
```xml
<dependencies>
    <dependency>
        <groupId>com.cxx</groupId>
        <artifactId>starter-web</artifactId>
        <version>2.0.0</version>
    </dependency>
    <dependency>
        <groupId>com.cxx</groupId>
        <artifactId>starter-jdbc</artifactId>
        <version>2.0.0</version>
    </dependency>
    <dependency>
        <groupId>com.cxx</groupId>
        <artifactId>starter-logging</artifactId>
        <version>2.0.0</version>
    </dependency>
</dependencies>
```
3. 打包模块时，需要添加spring-boot-maven-plugin
```xml
<plugin>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
```
