路由配置

网关将接入的请求根据路由策略来指定该请求的转发地址

路由配置示例1：

defaultRouter: clientChannel1
defaultNameSpace：null
pipeType: null
#本地识别器
localRecognizers:

- id: recognizer1
  keyMap: {channelId: '${channelId}'}
  type: map
- id: recognizer2
  keyMap: {pathToken: '${path}'}
  type: url
  values:
- available: true
  id: router1
  routerKey: ${channelId}
  routerMap: {a: helloworldService, b: clientChannel}
- available: true
  id: router2
  matcher: '${pathToken}->*myapp*'
  routerMap: {'${pathToken}->*.wsdl': wsdlService, '${pathToken}->*Service.json': helloworldService}
  type: default

首先尝试通过router1进行路由，通过map识别器，识别channelId，识别后通过路由表进行静态映射，假设${channelId}=a，则选择helloworldService进行路由.

如果channelId识别失败，或者识别后查找不到匹配的映射项，则尝试使用router2进行路由，检查${pathToken}是否含有"myapp"字符串。如果含有，尝试使用该路由项进行路由，router2没有配置routerKey，则对路由表中的映射项进行条件匹配,如果以“.wsdl”结尾，则选择wsdlService进行路由，如果以“Service.json”结尾，则选择helloworldService进行路由。

路由配置示例2：

#全局识别器
recognizer:
  values:

- id: recognizer4
  keyMap: {pathToken: '${path}'}
  type: url
- id: recognizer3
  keyMap: {all: '${all}'}
  type: all
- id: recognizer2
  keyMap: {host: '${host}', path: '${path[2..]}'}
  type: url
- id: recognizer1
  keyMap: {type: '${type}', busiId: '${head.busiId}', version: '${head.version}'}
  type: map
    available: true
    pipeType: direct
    inbound: true
  #路由
  router:
    values:
    #访问任意http://127.0.0.1:9000/*helloworld.json
- id: router1
  routerMap: {'${pathToken}->*helloworld.json': jsonChannel, '${pathToken}<>*helloworld.json && ${pathToken}->*.json': jsonChannelDynamic}
  available: true
  matcher: '${pathToken}->*.json && ${localPort}->9000'
  type: default
    #访问任意http://127.0.0.1:9001/*/ws/*
- id: router2
  routerMap: {'${pathToken}->*/ws/*': webserviceOutBoundChannel}
  available: true
  matcher: '${localPort}->9001 && ${pathToken}<>*wsdl'
  type: default
    #访问任意http://127.0.0.1:9001/*wsdl，路由到透传渠道，用来解析wsdl文件请求
- id: router3
  routerMap: {'${pathToken}->*wsdl': httpTransparentChannel}
  available: true
  matcher: '${localPort}->9001 && ${pathToken}->*wsdl'
  type: default
    #所有通过9002端口接入的请求，全部路由到http透传渠道
- id: router4
  routerMap: {'1->1': httpTransparentChannel}
  available: true
  matcher: '${localPort}->9002'
  type: default
    #所有通过9003端口接入的请求，全部路由到socket透传渠道
- id: router5
  routerMap: {'1->1': socketTransparentChannel}
  available: true
  matcher: '${localPort}->9003'
  type: default
  #所有通过9004端口接入的请求，socket定长，内容为xml
- id: router6
  routerMap: {'1->1': socketFixLengthXmlChannel}
  available: true
  matcher: '${localPort}->9004'
  type: default
    advancedDispatch: false
    available: true
    pipeType: direct

    inbound: true
    defaultRouter: httpTransparentChannel
