1. STS插件最好是要安装的.
2. 对应的Decompiler插件也是要安装的.
3. 如果遇到maven工程因为找不到包问题的, 在确认pom.xml 文件没有问题的情况下, 右键项目-Maven-Update Project 然后点击OK,更新一下工程,
还不行的 点击 Force Update of Snapshots/Releases
还不行的 删除.m2 Maven下载目录下的本地仓库所有文件,重新更新下载一遍
还不行的 在报错的Markers页签 右键删除报错信息
然后重新运行Spring Cloud
4.Spring-cloud 项目加入eureka后, restcontroller 默认返回的是xml格式,需要自定义一个配置类
1 @Configuration 2 public class WebMvcConfig extends WebMvcConfigurerAdapter { 3 4 //解决spring-cloud 加载eureka后, restcontroller 默认返回xml格式 5 @Override 6 public void configureContentNegotiation(ContentNegotiationConfigurer configurer) { 7 configurer.ignoreAcceptHeader(true).defaultContentType(MediaType.APPLICATION_JSON); 8 super.configureContentNegotiation(configurer); 9 } 10 }
5. 如果需要在项目一启动,就执行某些代码,可以增加如下的监听器代码
1 @Component 2 public class OnStartListener implements ApplicationListener<ContextRefreshedEvent> { 3 4 @Override 5 public void onApplicationEvent(ContextRefreshedEvent event) { 6 System.out.println(event.getApplicationContext().getParent()); 7 System.out.println("on start: " + System.currentTimeMillis()); 8 } 9 10 }
6.启动事务时,要在启动类加入一些注解
1 /** 2 * 启动类 3 * @author wunaozai 4 * MapperScan : 扫描的是mapper.xml中namespace指向的包位置 5 * EnableTransactionManagement : 加入事务 6 * 加入@Transaction 事务处理后, spring 会启用动态代理方式, 7 * 所以在EnableTransactionManagement 要增加proxyTargetClass 8 */ 9 @EnableEurekaClient 10 @SpringBootApplication 11 @EnableTransactionManagement(proxyTargetClass=true) 12 @MapperScan("com.wunaozai.xxx.center.mapper") 13 public class ServiceDeveloperCenterApplication { 14 15 public static void main(String[] args) { 16 SpringApplication.run(ServiceDeveloperCenterApplication.class, args); 17 } 18 }
7.项目中各个文件夹(包名)都最好按照默认的约定的来,不要自己乱改.
8.一份简单的application.properties
1 spring.application.name=service-developer-center 2 3 #server 4 server.port=9200 5 server.session.timeout=360000 6 server.session.cookie.name=IOT 7 8 #eureka 9 eureka.client.serviceUrl.defaultZone=http://172.16.23.203:9000/eureka/ 10 eureka.instance.prefer-ip-address=true 11 eureka.instance.instance-id=${spring.cloud.client.ipAddress}:${server.port} 12 13 #logging 14 logging.path=log 15 logging.level.com.favorites=INFO 16 logging.level.org.springframework.web=INFO 17 18 #datasource 19 spring.datasource.url=jdbc:postgresql://172.16.23.202:5432/service_developer_center 20 spring.datasource.username=postgres 21 spring.datasource.password= 22 spring.datasource.driverClassName=org.postgresql.Driver 23 24 #mybatis 25 mybatis.type-aliases-package=com.wunaozai.xxx.center.model 26 mybatis.mapper-locations=classpath:com/wunaozai/xxx/center/mapper/*.xml 27 28 #pagehelper 29 pagehelper.helperDialect=postgresql 30 pagehelper.reasonable=true 31 pagehelper.supportMethodsArguments=true 32 pagehelper.returnPageInfo=check 33 34 #redis 35 spring.redis.database=0 36 spring.redis.host=172.16.20.229 37 spring.redis.port=6379 38 spring.redis.password= 39 spring.redis.timeout=0 40 spring.redis.pool.max-active=8 41 spring.redis.pool.max-wait=-1 42 spring.redis.pool.max-idle=8 43 spring.redis.pool.min-idle=0 44 spring.cache.type=Redis 45 46 #thymeleaf 47 spring.thymeleaf.mode=HTML5 48 spring.thymeleaf.encoding=UTF-8 49 spring.thymeleaf.content-type=text/html 50 spring.thymeleaf.cache=false 51 52 #upload max file size 53 spring.http.multipart.maxFileSize=25Mb 54 spring.http.multipart.maxRequestSize=50Mb 55 56 #email config 57 spring.mail.host=192.168.8.208 58 spring.mail.username=xxx@wunaozai.com 59 spring.mail.password= 60 srping.mail.default-encoding=UTF-8
9.一份简单的 pom.xml
