标签: applicationcontext

我们有一个托管在共享 tomcat 实例上的 Spring 应用程序。

有时我们必须重新加载 spring 应用程序上下文但不想重新启动 Tomcat 服务器，因为其他应用程序也托管在那里。

是否通过以下方式刷新 springs 应用程序上下文

  ((ConfigurableApplicationContext)applicationContext).refresh();

被认为是不好的做法？

我有哪些选择？

我的应用程序我有一个application-context.xml.现在我将ApplicationContext实例化为:

ApplicationContext context = new ClassPathXmlApplicationContext("application-context.xml");

是否可以通过此实例化传递参数,以便这些参数可用于初始化某些bean的某些属性？

PS:不使用属性文件.由于参数是生成运行时间,如可解决的jar的位置,系统架构,os名称等是可变的.

不确定这是否有答案,但这里有.我正在使用JUnit 4.8.1来测试我的Spring 3.1.0.RELEASE项目.我的classpath上有两个JAR文件.在每个文件中,都有相同名称的文件 - /module/rootContext.xml.

在我的testApplicationContext.xml文件(我的JUnit测试的Spring上下文文件)中,是否可以包含其中的每一个？现在,我唯一知道该怎么做的是

<import resource="classpath:/module/rootContext.xml" />

但我不知道如何指定每个文件所在的确切JAR文件.

因为我正在处理不属于我自己的代码,所以不能更改JAR中XML文件的名称.

我正在为一个复杂的弹簧应用程序编写单元测试.我想加载spring上下文以使用定义的bean.我的context.xml位于:

src/main/resources/context.xml

在maven构建之后,context.xml出现在:

target/classes/context.xml

在pom.xml中,我有:(正如所建议的这个帖子)

<resources>
    <resource>
        <filtering>true</filtering>
        <directory>src/test/resources</directory>
        <includes>
            <include>**/*.properties</include>
        </includes>
        <excludes>
            <exclude>**/*local.properties</exclude>
        </excludes>
    </resource>
    <resource>
        <directory>src/main/resources</directory>
        <includes>
            <include>**/*.properties</include>
            <include>**/*.xml</include>
        </includes>
    </resource>
</resources>

我试图通过两种方式完成这项工作:

1, Use ApplicationContext
AppliactionContext springContext = new ClassPathXmlApplicationContext("/context.xml");
MyObject myObject = springContext.getBean(myObject.class);

2, Use Annotations
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"/context.xml"})
public class myTest{
    @Autowired
    MyObject myObject;
    ...
}

但这两种方式都不适合我.错误信息:

我试图根据这个官方的Apache CXF指南为我的基于CXF的客户端配置SSL支持,但Eclipse标记了带有红色下划线和非常短的错误描述的标记:http:conduit

  The prefix "http" for element "http:conduit" is not bound

我在网上搜索了关于此消息的含义以及如何修复它的其他线索,但我还没有找到任何可以解释为什么我收到此错误的信息.

知道元素"http:conduit"的前缀"http"是不是绑定意味着什么？

绑定到什么？

为什么只有前缀"http"而不是"管道"？

我有一个奇怪的错误,我在互联网上搜索了很多.我无法理解为什么我收到此错误.我在春季jira上找到了关于这个错误的一些解释.我有context:component-scan,applicationContext.xml我在com.sow.webservices包中定义了5个包.但是,当我添加包含控制器类的控制器包时,我抛出

Error occured processing XML '[Ljava.lang.String; cannot be cast to java.lang.String'. See Error Log for more details

这是组件扫描:

<context:component-scan base-package="com.sow.webservices.aop, 
                                          com.sow.webservices.exceptions,
                                          com.sow.webservices.models, 
                                          com.sow.webservices.services,
                                          com.sow.webservices.controller">

我想向您展示整个异常跟踪.感谢您的帮助.

我有这个配置类：

@ComponentScan(
        basePackages = { 
                "mypackage.controller",
                "mypackage.service",
                "mypackage.repository" 
        }
)
@TestPropertySource(locations="classpath:configuration.properties")
@Import({
    H2Configuration.class
})
public class TestConfiguration {
}

@Configuration
public class H2Configuration {

    @Bean
    public DataSource dataSource() throws SQLException {
        EmbeddedDatabaseBuilder builder = new EmbeddedDatabaseBuilder();
        EmbeddedDatabase db = builder
                .setType(EmbeddedDatabaseType.H2)
                .addScript("h2/create.sql")
                .addScript("h2/insert.sql")
                .build();
        db.getConnection().setAutoCommit(false);
        return db;
    }

}

我有这两个班级测试：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(loader=AnnotationConfigContextLoader.class, classes = { TestConfiguration.class })
public class FirstRepositoryTest {

    @Autowired
    MyFirstRepositoryImpl repository;

    @Before
    public void initTest() {
    }

    @Test(expected = NullPointerException.class)
    public void testNullRecords() {
        repository.foo(null, null);
    } …

我卸载了MyEclipse4S并重新安装它并从工作区运行项目并开始获得以下异常.我有

/WEB-INF/applicationContext.xml在正确的位置:(我的上下文文件位于底部.

基本上我有这个Outer.jar,在它中声明是一个带有组件扫描的应用程序上下文:

<context:component-scan
        base-package="x.y.z.class" />

然而,这x.y.z.class是在inner.jar中,它是outer.jar的依赖,

我收到一个错误,找不到类.../Outer.jar/x/y/z/class,怎么指定检查inner.jar？

更新:初始化应用程序上下文:

 org.springframework.context.ApplicationContext ctx = 
                 new ClassPathXmlApplicationContext("applicationContext.xml");

exception: I/O failure during classpath scanning; nested exception is java.io.FileNotFoundException: ..\default\deploy\test.war\WEB-INF\lib\inner.jar\x\y\z
 and it says inner.jar/x/y/z/class not found

Outer.jar将inner.jar作为依赖项

我是春天和maven的新手.我有一个使用Spring的简单hello world项目.项目构建成功但我在运行时遇到以下错误:

Error: A JNI error has occurred, please check your installation and try again
Exception in thread "main" java.lang.NoClassDefFoundError: org/springframework/context/ApplicationContext

这是主要的应用程序:App.java

package com.test.SpringMaven2;

import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.AnnotationConfigApplicationContext;



/**
 * Hello world!
 *
 */
public class App 
{
    public static void main( String[] args )
    {
        System.out.println( "Hello World!" );
        System.out.println( "Hello World!" );
        ApplicationContext context = new AnnotationConfigApplicationContext(HelloWorldConfig.class);

        HelloWorld hello = (HelloWorld) context.getBean("helloWorld"); 
        hello.setName("Adnan");
        hello.getName();
    }
}

这是HelloWorld bean

package com.test.SpringMaven2;

public class HelloWorld{


    private String name; 

    public void …
