tomcat 結合spring security 配置SSL認證

小結一下tomcat搭配spring security作ssl，其實單tomcat就能夠搞你的應用 
ssl認證了，這裏只不過順道使用了spring secruity（若是你的應用是用了 
spring security的話）。 

1 首先是製做證書了，步驟比較傳統，簡單帶過，不懂的請去google 

   keytool -genkey -alias MyKeyAlias -keyalg RSA -keystore /home/test.keystore 

而後回答一大堆問題，最後生成自簽證書 

2 tomcat的conf目錄中的sevrer.xml中，配置以下： 

<Connector SSLEnabled='true' keystoreFile='/home/test.keystore' keystorePass='password' port='8443' scheme='https' secure='true' sslProtocol='TLS'/> 


3 若是不使用spring security的話，須要這樣在web.xml中配置 

<security-constraint> 
    <web-resource-collection> 
        <web-resource-name>my-secure-app</web-resource-name> 
        <url-pattern>/*</url-pattern> 
    </web-resource-collection> 
    <user-data-constraint> 
        <transport-guarantee>CONFIDENTIAL</transport-guarantee> 
    </user-data-constraint> 
</security-constraint> 

  若是使用spring security，則這樣： 

<filter>
    <filter-name>springSecurityFilterChain</filter-name>
    <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
  </filter>
  <filter-mapping>
    <filter-name>springSecurityFilterChain</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>

<context-param>
          <param-name>contextConfigLocation</param-name>
          <param-value>/WEB-INF/spring/root-context.xml
           /WEB-INF/spring/appServlet/application-security.xml           
          </param-value>
     </context-param>

而後application-security.xml中：

<?xml version='1.0' encoding='UTF-8'?>
<beans:beans xmlns='http://www.springframework.org/schema/security'
  xmlns:beans='http://www.springframework.org/schema/beans'
  xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'
  xsi:schemaLocation='http://www.springframework.org/schema/beans

http://www.springframework.org/schema/beans/spring-beans-3.0.xsd


http://www.springframework.org/schema/security


http://www.springframework.org/schema/security/spring-security-3.1.xsd'>

       <http auto-config='true' >
          <intercept-url pattern='/**' requires-channel='https' />    
       </http>

       <authentication-manager>
       </authentication-manager>

</beans:beans>

這裏用intercept-url，能夠很方便配置，哪些鏈接要用https,哪些不用了
