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
