今天公司要求把Web版客户端全部加上https,这里记录一下实现过程:
?
1.添加KeyPair:
在命令行模式下切换到目录%TOMCAT_HOME%,使用jdk的keytool工具,
keytool -genkey -alias tomcat -keyalg RSA -keypass password -storepass password -keystore name.keystore -validity 3600
其中-validity 3600是过期时间,单位是天,默认是90天
?
2.将证书导入的JDK的证书信任库中:
keytool -export -trustcacerts -alias tomcat -file server.cer -keystore
server.keystore -storepass password
keytool -import -trustcacerts -alias tomcat -file server.cer -keystore
%JAVA_HOME%/jre/lib/security/cacerts -storepass password
这里注意tomcat使用的是哪个jre
如果本来目录中的cacerts存在,会报个错,把原来的cacerts备份一下,换个名字就可以了
?
3.配置tomcat https端口:
<Connector port="8443" protocol="HTTP/1.1" SSLEnabled="true"??
??? ??? maxThreads="150" scheme="https"
??? ??? secure="true" clientAuth="false" keystoreFile="d:\elitecrm.cer"
??? ??? keystorePass="letmein" sslProtocol="TLS" />
4.如果有需要,可以再配置压缩
<Connector port="8443" protocol="HTTP/1.1" SSLEnabled="true"??
??? ??? maxThreads="150" scheme="https"
??? ??? secure="true" clientAuth="false" keystoreFile="d:\elite.keystore"
??? ??? keystorePass="letmein" sslProtocol="TLS" compression="on"
??????? compressionMinSize="2048"
??????? noCompressionUserAgents="gozilla, traviata"
??????? compressableMimeType="text/html,text/xml,text/javascript,text/css,text/plain"/>
compression设为on打开压缩
compressionMinSize为启用压缩的阀值,设置这个值要综合考虑压缩的代价和网络传输代价的平衡值。
noCompressionUserAgents设置对于何种类型的浏览器不启用压缩
compressableMimeType设置对于哪些数据类型启用压缩,对于我们的客户端,text/html和text/xml要启用。
?
这样就可以用https协议8443端口访问之前的url,但是如果要用java.net.URL类来访问https的内容,还需要修改部分代码:
下面是一个用java.net.URL类来做ajax跨域代理的工具类,其中使用了模拟的post请求,并且配置了HttpsCertificates
其中配置SSL的信任证书这块是网上找到的,具体的作用还不是完全明白,不过这样以前的应用就又能正常使用了。
