SpringBoot注册多个MessageDispatcherServlet遇404问题求助

1. 修正MessageDispatcherServlet的Bean定义方法名 #

Java不允许同一个类中存在同名同参数列表的方法，你代码里两个创建MessageDispatcherServlet的方法名完全重复，即使指定了name属性也会导致Bean创建逻辑异常。修改方法名以区分两个Bean：

@Bean(name="a_servlet")
public MessageDispatcherServlet aMessageDispatcherServlet(WebApplicationContext context) {
    MessageDispatcherServlet servlet = new MessageDispatcherServlet(context);
    servlet.setTransformWsdlLocation(true);
    // 无需重复调用setApplicationContext，构造函数已传入上下文
    return servlet;
}

@Bean(name="b_servlet")
public MessageDispatcherServlet bMessageDispatcherServlet(WebApplicationContext context, @Qualifier("soap12MessageFactory") SaajSoapMessageFactory soap12MessageFactory) {
    MessageDispatcherServlet servlet = new MessageDispatcherServlet(context);
    servlet.setTransformWsdlLocation(true);
    servlet.setMessageFactory(soap12MessageFactory); // 绑定SOAP1.2消息工厂
    return servlet;
}

2. 配置SOAP1.2专属消息工厂 #

为/soap/b/*对应的Servlet创建SOAP1.2版本的消息工厂Bean，/soap/a/*默认使用SOAP1.1工厂无需额外配置：

@Bean
public SaajSoapMessageFactory soap12MessageFactory() {
    SaajSoapMessageFactory factory = new SaajSoapMessageFactory();
    factory.setSoapVersion(SoapVersion.SOAP_12);
    return factory;
}

3. 让Spring MVC避开SOAP请求路径 #

Spring Boot默认的Spring MVC DispatcherServlet映射路径为/*，会优先拦截所有请求，导致你的MessageDispatcherServlet无法处理/soap/b/*请求。在application.properties中添加配置排除该路径：

spring.mvc.servlet.exclude-path-patterns=/soap/**

4. 提升MessageDispatcherServlet的处理优先级 #

设置ServletRegistrationBean的order属性，确保你的SOAP Servlet比Spring MVC的DispatcherServlet拥有更高的处理优先级（数值越小优先级越高）：

@Bean
public ServletRegistrationBean aDispatcherServlet(@Qualifier("a_servlet") MessageDispatcherServlet servlet) {
    ServletRegistrationBean<MessageDispatcherServlet> registration = new ServletRegistrationBean<>(servlet, "/soap/a/*");
    registration.setOrder(1); // 高于Spring MVC默认的order=2
    return registration;
}

@Bean
public ServletRegistrationBean bDispatcherServlet(@Qualifier("b_servlet") MessageDispatcherServlet servlet) {
    ServletRegistrationBean<MessageDispatcherServlet> registration = new ServletRegistrationBean<>(servlet, "/soap/b/*");
    registration.setOrder(1);
    return registration;
}

5. 验证配置 #

重启应用后访问actuator/mappings，应该能看到/soap/a/*和/soap/b/*的映射条目，此时发送SOAP1.2请求到/soap/b/*即可正常处理。
