Spring Boot 项目指南
目录
使用 gradle 作为构建工具。
使用 IDEA,选择创建新项目,选择 Spring Initializer ,然后选择依赖和填写项目相关信息即可。
目前用到的依赖:
dependencies {
implementation 'org.springframework.boot:spring-boot-starter-amqp'
implementation 'org.springframework.boot:spring-boot-starter-data-mongodb'
implementation 'org.springframework.boot:spring-boot-starter-data-redis'
implementation 'org.springframework.boot:spring-boot-starter-mail'
implementation 'org.springframework.boot:spring-boot-starter-quartz'
implementation 'org.springframework.boot:spring-boot-starter-validation'
implementation 'org.springframework.boot:spring-boot-starter-web'
implementation 'org.springframework.boot:spring-boot-starter-websocket'
implementation 'org.mybatis.spring.boot:mybatis-spring-boot-starter:2.1.2'
implementation 'org.springframework.session:spring-session-data-redis'
compileOnly 'org.projectlombok:lombok'
runtimeOnly 'mysql:mysql-connector-java'
annotationProcessor 'org.projectlombok:lombok'
testImplementation('org.springframework.boot:spring-boot-starter-test') {
exclude group: 'org.junit.vintage', module: 'junit-vintage-engine'
}
testImplementation 'org.springframework.amqp:spring-rabbit-test'
compile 'com.baomidou:mybatis-plus-boot-starter:3.3.1.tmp' // mybatis-plus
compile 'com.baomidou:mybatis-plus-generator:3.3.1.tmp' // mybatis-plus-generator
compile 'org.apache.velocity:velocity-engine-core:2.2' // velocity
compile 'io.springfox:springfox-swagger2:2.9.2' // swagger2
compile 'io.springfox:springfox-swagger-ui:2.9.2' //swagger2-ui
}
然后需要使用公共代理库,加快依赖获取速度:
repositories {
maven {
url "https://maven.aliyun.com/repository/central"
}
}
配置数据库:
user.host=192.168.122.7
spring.main.banner-mode=off
spring.data.mongodb.host=${user.host}
spring.data.mongodb.port=27017
spring.data.mongodb.database=spas
spring.redis.host=${user.host}
spring.redis.port=6379
spring.redis.password=Passw0rd!
spring.datasource.username=spas
spring.datasource.password=Passw0rd!
spring.datasource.url=jdbc:mysql://${user.host}:3306/spas?useUnicode=true&characterEncoding=utf-8&useSSL=true&serverTimezone=UTC
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.datasource.type=com.alibaba.druid.pool.DruidDataSource
配置 Swagger2:
@Configuration
@EnableSwagger2
public class Swagger2Configuration {
public ApiInfo apiInfo(){
return new ApiInfoBuilder()
.title("检察建议流程辅助办案系统")
.description("API 接口文档")
.version("1.0")
.build();
}
@Bean
public Docket createRestApi() {
return new Docket(DocumentationType.SWAGGER_2)
.apiInfo(apiInfo())
.select()
.apis(RequestHandlerSelectors.basePackage("com.spas.backend"))
.paths(PathSelectors.any())
.build();
}
}
编写并启动代码生成器:

}
});
/*

*/
cfg.setFileOutConfigList(focList);
mpg.setCfg(cfg);
// 配置模板

在代码生成器生成的文件中,添加应有的信息
