在我的项目中,我开始使用c3p0和hibernate重新连接到数据库,因为hibernate不会在db失败时恢复连接.

<dependency>
            <groupId>org.hibernate</groupId>
            <artifactId>hibernate-c3p0</artifactId>
            <version>5.2.9.Final</version>
</dependency>

我正在使用hibernate版本:

<dependency>
            <groupId>org.hibernate</groupId>
            <artifactId>hibernate-core</artifactId>
            <version>5.2.9.Final</version>
</dependency>

postgresql驱动程序是:

<dependency>
            <groupId>org.postgresql</groupId>
            <artifactId>postgresql</artifactId>
            <version>42.1.4</version>
</dependency>

c3p0配置是:

 properties.put("hibernate.c3p0.preferredTestQuery","SELECT 1");
    properties.put("hibernate.c3p0.testConnectionOnCheckout","true");
    properties.put("hibernate.c3p0.acquireRetryAttempts","1");
    properties.put("hibernate.c3p0.acquireIncrement","1");
    properties.put("hibernate.c3p0.idleConnectionTestPeriod","60");

但我一直收到这个错误:

我已经读到您需要实体类的kotlin-maven-noarg编译器插件，以便它生成默认参数少的cosntructor。

但是应用程序未启动并出现以下错误：

没有实体的默认构造函数

你能告诉我我在做什么错吗？

我有一个spring-boot 2.1.2.RELEASE应用程序，该应用程序使用嵌入式tomcat Web服务器并通过其SDK 使用OpenKM。

现在，我有一些集成测试，这些测试使用restassuredlib进行REST调用并验证响应结构。我的想法是将其集成OpenKM.war到此嵌入式tomcat中，并能够运行此测试，而无需在其他服务器上运行openkm应用程序。

这就是我使嵌入式tomcat读取和部署openkm.war的方式：

@Configuration
public class TomcatConfig {
    @Bean
    public ServletWebServerFactory servletContainer() {
        TomcatServletWebServerFactory tomcat = new TomcatServletWebServerFactory() {
            @Override
            protected void postProcessContext(Context context) {
                SecurityConstraint securityConstraint = new SecurityConstraint();
                securityConstraint.setUserConstraint("CONFIDENTIAL");
                SecurityCollection collection = new SecurityCollection();
                collection.addPattern("/*");
                securityConstraint.addCollection(collection);
                context.addConstraint(securityConstraint);
            }

            @Override
            protected TomcatWebServer getTomcatWebServer(Tomcat tomcat) {
                new File(tomcat.getServer().getCatalinaBase(), "webapp").mkdirs();
                try {
                    tomcat.addWebapp("/okm", new ClassPathResource("webapp/openkm.war").getFile().toString());
                } catch (Exception ex) {
                    throw new IllegalStateException("Failed to add okm", ex);
                }
                return super.getTomcatWebServer(tomcat);
            }
        }; …

所以,这是我在REST调用我的服务后得到的:

我是Maven的新手,我试图用一些框架创建自己的Java EE Maven项目......我已经开始使用两个模块和一个父模块.问题是我在发出mvn clean时遇到此错误:

[ERROR] The projects in the reactor contain a cyclic reference: Edge between 'Vertex{label='org.tepo:Jporto-web:0.0.1-SNAPSHOT'}' and 'Vertex{label='org.tepo:Jporto-ejb:0.0.1-SNAPSHOT'}' introduces to cycle in the graph org.tepo:Jporto-ejb:0.0.1-SNAPSHOT --> org.tepo:Jporto-web:0.0.1-SNAPSHOT --> org.tepo:Jporto-ejb:0.0.1-SNAPSHOT -> [Help 1]

我制作了一个http拦截器,我需要在其中评估responese头并找到特定的(授权).拦截器本身正在工作但它无法列出我在服务器端设置的标头,我可以清楚地看到设置在firebug的网络选项卡中.

拦截器:

app.factory('HttpItc', function($q, $localStorage, $injector) {
return {
response: function (response) {
   //console.log(response); // Contains the data from the response.

  var freshJwt = response.headers['Authorization'];

  if (freshJwt) {
    $localStorage.jwt = freshJwt;
  }

  // Return the response or promise.
  return response;
}  };});

这是我在服务器端Express中设置标头的方法:

return res
                    .header('Authorization', jwt)
                    .header('testHeader', 'testValue')
                    .json(user);

怎么了？如何在http的拦截器中访问响应头？
