有没有办法根据分散在各个类中的Spring 3注释生成完整的XML配置文件？

理想情况下,我正在寻找一种可以"解析"Spring 3项目并输出XML配置的工具,就像xdoclet正在做的那样(但是从Spring注释中脱离)

有没有像这样的工具,或者如果不存在的话我可以自己写一个方法？

正如在上面的标题中,我很困惑通过直接@Autowired注释注入applicationContext或在单例spring bean中实现ApplicationContextAware接口之间的优缺点.

您更喜欢哪一种？为什么？谢谢.

我正在使用Spring的转换服务,并在其中注册了我自己的转换器:

public class MyTypeConverter implements Converter<String, MyType> {
    @Override
    public Currency convert(String text) {
        MyType object = new MyType();
        // do some more work here...
        return object;
    }
}

现在,在我的应用程序中,我可以进行转换String,MyType并且运行良好:

@Autowired
private ConversionService cs;

public void doIt() {
    MyType object = cs.convert("Value1", MyType.class);
}

但是我也注意到,例如,我可以在我的MVC控制器中使用相同的转换器,它也以某种方式处理列表:

@RequestMapping(method = RequestMethod.GET, value = "...")
@ResponseBody
public final String doIt(@RequestParam("param1") List<MyType> objects) throws Exception {
    // ....
}

因此,如果我param1=value1,value2在控制器中提交,我会收到一个List<MyType>包含两个元素的内容.所以spring会用逗号分割String,然后将每个元素分别转换为MyType.是否有可能以编程方式执行此操作？

我需要类似这样的东西:

List<MyType> objects = cs.convert("Value1,Value2", …

为什么spring没有绑定嵌套对象上的值？

尽管在视图中使用bean表示法在表单中进行设置,但RegistrationBean上的SecurityQuestion对象分别设置为问题和答案为null,null.

豆子:

public class SecurityQuestion {
  SecurityQuestionType type;
  String answer;
}

public class RegistrationBean {
  @Valid
  SecurityQuestion securityQuestion;
  String name;


  public SecurityQuestionType[] getSecurityQuestionOptions() {
    return SecurityQuestionType.values();
  }
}

视图:

<form:form modelAttribute="registrationBean" method="POST">
  <form:select id="securityQuestion" path="securityQuestion.question">
    <c:forEach var="securityQuestionOption" items="${securityQuestionOptions}">
      <form:option value="${securityQuestionOption}">${securityQuestionOption</form:option>
    </c:forEach>
  </form:select>

  <form:input id="securityAnswer" path="securityQuestion.answer" />
  <form:input id="name" path="name" />
</form:form>

控制器:

@RequestMapping(value = URL_PATTERN, method = RequestMethod.POST)
public ModelAndView submit(@Valid final RegistrationBean registrationBean) {
  // registrationBean.getSecurityQuestion().getQuestion() == null
  // registrationBean.getSecurityQuestion().getAnswer() == null
}

解

所有bean都必须拥有所有字段的getter/setter.Spring使用默认构造函数,然后使用setter从视图中改变对象.

所以当我尝试从jconsole连接到jmx时,我得到了这个异常:

Caused by: java.rmi.ConnectException: Connection refused to host: 78.84.17.116; nested exception is: 
    java.net.ConnectException: Connection timed out: connect
    at sun.rmi.transport.tcp.TCPEndpoint.newSocket(TCPEndpoint.java:601)
    at sun.rmi.transport.tcp.TCPChannel.createConnection(TCPChannel.java:198)
    ...

我试图在jconsole中连接到这样的url: service:jmx:rmi:///jndi/rmi://78.84.17.116:43030/test

我的jmx spring配置:

        class="org.springframework.jmx.support.ConnectorServerFactoryBean"
        depends-on="rmiRegistry" p:objectName="connector:name=rmi" …

我尝试了这里的答案:Hibernate Validator,自定义ResourceBundleLocator和Spring

但仍然只是{location.title.notEmpty}作为输出而不是消息.

调度员servlet.xml中

<bean name="validator"
    class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean">
    <property name="validationMessageSource">
        <ref bean="resourceBundleLocator"/>
    </property>
</bean>

<bean name="resourceBundleLocator" class="org.springframework.context.support.ReloadableResourceBundleMessageSource">
    <property name="basenames">
        <list>
            <value>/WEB-INF/validationMessages</value>
        </list>
    </property>
</bean>

/WEB-INF/validationMessages.properties:

location.title.notEmpty=My custom message

表格(课程地点)

@NotEmpty( message = "{location.title.notEmpty}" )
private String title;

这里出了什么问题？

我可以在方法中使用@value注释来读取属性吗？

    void method1(){

     @Value("#{AppProperties['service.name']}") String name;
     -------
      -------
   } 

我有一个带Maven的多模块Spring项目.我正在使用Spring 3.2.3和注释配置.

我有以下布局:

parent
    common  (depends on parent)
    webapp  (depends on parent, common, module1, module2)
    module1 (depends on parent)
    module2 (depends on parent)

我需要它common,module1并且module2可以指定自己的i18n属性(并webapp收集这些文件并以某种方式提供它们？!):

common:  src/main/resources/i18n/messages_en.properties
module1: src/main/resources/i18n/messages_en.properties
module2: src/main/resources/i18n/messages_en.properties

我试过用

@Bean
public MessageSource messageSource() {
    ReloadableResourceBundleMessageSource messageSource = new ReloadableResourceBundleMessageSource();
    messageSource.setBasename("classpath:/i18n/messages");
    messageSource.setDefaultEncoding("UTF-8");
    messageSource.setUseCodeAsDefaultMessage(true);
    return messageSource;
}

但是看起来Spring只会使用其中一个翻译文件,而是应该使用all.

另一种可能性是为每个模块指定一个唯一的属性文件名,但后来我不知道要设置的基本名称messageSource.setBasename(...).

谢谢你的帮助!

在我的Web应用程序中,当我尝试注销时,它将转到给j_spring_security_logout定的页面.在我的spring-security.xml页面中,我添加了

<logout logout-success-url="/login" delete-cookies="JSESSIONID" />

当我使用spring security 3.1.4.RELEASE版本时,问题就是这个问题.现在我正在使用3.2.2.RELEASE

我也尝试了以下内容.没工作

<logout logout-url="/logout" delete-cookies="JSESSIONID" />

弹簧security.xml文件

我想像这样做@CrossOrigin:

@CrossOrigin(origins = "http://domain2.com")
@RequestMapping("/{id}")
public Account retrieve(@PathVariable Long id) {
    // ...
}

(假设升级到Spring 4受到限制)目前我在Spring 3中所要做的就是这样:

public class CORSFilter implements Filter {
    public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException {
        HttpServletResponse response = (HttpServletResponse) res;
        HttpServletRequest request= (HttpServletRequest) req;
        response.setHeader("Access-Control-Allow-Origin", "*");
        response.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE");
        response.setHeader("Access-Control-Allow-Headers", "x-requested-with");
        response.setHeader("Access-Control-Expose-Headers", "x-requested-with"); chain.doFilter(req, res);
    }
}

请注意,@CrossOriginSpring 4.2中的实现源是在这里.

我的问题是:如何在Spring 3中进行@CrossOrigin注释？
