1.配置pom.xml

資料庫使用mysql,使用mybatis-plus作為連線資料庫工具
2.配置application.yml3.編寫主要的生成工具類：# Tomcat server: tomcat: max-threads: 10 min-spare-threads: 10 port: 7777 # mysql spring: datasource: type: com.alibaba.druid.pool.DruidDataSource driverClassName: com.mysql.jdbc.Driver url: jdbc:mysql://localhost:3306/ag_admin?useUnicode=true&characterEncoding=UTF-8&useSSL=false username: root password: 123456 jackson: time-zone: GMT+8 date-format: yyyy-MM-dd HH:mm:ss thymeleaf: mode: LEGACYHTML5 cache: false # Mybatis配置 mybatis: mapperLocations: classpath:mapper/*.xml #mybatis mybatis-plus: mapper-locations: classpath:mapper/*.xml #實體掃描，多個package用逗號或者分號分隔 typeAliasesPackage: com.gameley.generator.entity global-config: #主鍵型別 0:"資料庫ID自增", 1:"使用者輸入ID",2:"全域性唯一ID (數字型別唯一ID)", 3:"全域性唯一ID UUID"; id-type: 0 #欄位策略 0:"忽略判斷",1:"非 NULL 判斷"),2:"非空判斷" field-strategy: 2 #駝峰下劃線轉換 db-column-underline: true #重新整理mapper 除錯神器 refresh-mapper: true #資料庫大寫下劃線轉換 #capital-mode: true #序列介面實現類配置 #key-generator: cn.jeefast.xxx #邏輯刪除配置 logic-delete-value: 0 logic-not-delete-value: 1 #自定義填充策略介面實現 #meta-object-handler: cn.jeefast.xxx #自定義SQL注入器 #sql-injector: cn.jeefast.xxx configuration: map-underscore-to-camel-case: true cache-enabled: false

增加springcloud-bus，以實現自動配置
1.在兩個工程的pom.xml中引入
<!--訊息匯流排-->
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-bus-amqp</artifactId>
</dependency>
<!--config-->
<dependency>

@Slf4j
@Configuration
@RefreshScope
public class DruidConfiguration {
@Value("${spring.datasource.url}")
private String dbUrl;
@Value("${spring.datasource.username}")
private String username;
@Value("${spring.datasource.password}")
private String password;
@Bean //宣告其為Bean例項
@Primary //在同樣的DataSource中，首先使用被標註的DataSource
@RefreshScope
public DataSource dataSource(){
DruidDataSource datasource = new DruidDataSource();
datasource.setUrl(dbUrl);
datasource.setUsername(username);
datasource.setPassword(password);
return datasource;
}
}增加的url,例如：
http://{ip}:8888/bus/refresh
如需設定密碼，則在config中增加配置
encrypt:
key: 123456
