升级sts4 ,碰到的坑,maven打jar包,ehcache的内存泄露
之前,在eclipse 2019中,新建springboot项目 pom出错,需要改
<!-- <maven-jar-plugin.version>3.1.1</maven-jar-plugin.version> -->
现在这句可以废弃不用了,默认的sts4带的,就可以。
在maven打jar包,仍会碰到无法把jsp页面,包进去的情况,,1.4.2的版本,仍需表明。
<plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> <version>1.4.2.RELEASE</version> <configuration> <mainClass>cn.taotao.Zhouyi3Application</mainClass> <excludes> <exclude> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> </exclude> </excludes> </configuration> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-resources-plugin</artifactId> <configuration> <encoding>UTF-8</encoding> <useDefaultDelimiters>true</useDefaultDelimiters> </configuration> </plugin> </plugins>
在ehcache中,出现大量的驻留内存。
使用这个方法,测试去掉ehcache的内存泄露
@Configuration public class EhcacheListenerConfig { @Bean public IntrospectorCleanupListener introspectorCleanupListener() { return new IntrospectorCleanupListener(); } @Bean public ServletListenerRegistrationBean<IntrospectorCleanupListener> servletListenerRegistrationBean(IntrospectorCleanupListener myListener){ ServletListenerRegistrationBean<IntrospectorCleanupListener> registrationBean = new ServletListenerRegistrationBean<IntrospectorCleanupListener>(); registrationBean.setListener(myListener); return registrationBean; } }
