# 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
|
||
  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。
|
||
  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
|
||
  该模块主要是一些通用的配置。
|
||
|
||
### 3.3.1 data
|
||
  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
|
||
  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
|
||
  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。
|
||
  该模块的pom.xml声明的依赖会注入到实际的项目中。
|
||
  在springboot3中，可以在**main->resources->META-INF->spring->org.springframework.boot.autoconfigure.AutoConfiguration.imports**中声明需要自动执行的类。
|
||
|
||
#### 3.4.1 stater-jdbc
|
||
  该模块主要提供数据库相关的配置功能。
|
||
  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());
|
||
}
|
||
}
|
||
}
|
||
```
|
||
:::
|
||
|
||
  `@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。
|
||
  `@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
|
||
  该模块主要提供web相关的配置功能。
|
||
  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

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

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

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>
|
||
```
|
||
|
||
  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>
|
||
```
|
||
|
||
  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>
|
||
``` |
