今天就跟大家聊聊有關使用spring boot如何實現對CAS進行整合，可能很多人都不太了解，為了讓大家更加了解，小編給大家總結了以下內容，希望大家根據這篇文章可以有所收獲。
代碼整合cas的重要過程

} 2.為了讓你們更省力且直接的看到效果，我把相關配置也貼出來
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Configuration;
import java.util.Arrays;
import java.util.List;
@ConfigurationProperties(prefix = "spring.cas")
public class SpringCasAutoconfig {
static final String separator = ",";
private String validateFilters;
private String signOutFilters;
private String authFilters;
private String assertionFilters;
private String requestWrapperFilters;
private String casServerUrlPrefix;
private String casServerLoginUrl;
private String serverName;
private boolean useSession = true;
private boolean redirectAfterValidation = true;
public List<String> getValidateFilters() {
return Arrays.asList(validateFilters.split(separator));
}
public void setValidateFilters(String validateFilters) {
this.validateFilters = validateFilters;
}
public List<String> getSignOutFilters() {
return Arrays.asList(signOutFilters.split(separator));
}
public void setSignOutFilters(String signOutFilters) {
this.signOutFilters = signOutFilters;
}
public List<String> getAuthFilters() {
return Arrays.asList(authFilters.split(separator));
}
public void setAuthFilters(String authFilters) {
this.authFilters = authFilters;
}
public List<String> getAssertionFilters() {
return Arrays.asList(assertionFilters.split(separator));
}
public void setAssertionFilters(String assertionFilters) {
this.assertionFilters = assertionFilters;
}
public List<String> getRequestWrapperFilters() {
return Arrays.asList(requestWrapperFilters.split(separator));
}
public void setRequestWrapperFilters(String requestWrapperFilters) {
this.requestWrapperFilters = requestWrapperFilters;
}
public String getCasServerUrlPrefix() {
return casServerUrlPrefix;
}
public void setCasServerUrlPrefix(String casServerUrlPrefix) {
this.casServerUrlPrefix = casServerUrlPrefix;
}
public String getCasServerLoginUrl() {
return casServerLoginUrl;
}
public void setCasServerLoginUrl(String casServerLoginUrl) {
this.casServerLoginUrl = casServerLoginUrl;
}
public String getServerName() {
return serverName;
}
public void setServerName(String serverName) {
this.serverName = serverName;
}
public boolean isRedirectAfterValidation() {
return redirectAfterValidation;
}
public void setRedirectAfterValidation(boolean redirectAfterValidation) {
this.redirectAfterValidation = redirectAfterValidation;
}
public boolean isUseSession() {
return useSession;
}
public void setUseSession(boolean useSession) {
this.useSession = useSession;
}
}
3.配置文件 dev.yml
#cas client config spring:cas: sign-out-filters: /logout auth-filters: /* validate-filters: /* request-wrapper-filters: /* assertion-filters: /* cas-server-login-url: cas登錄url cas-server-url-prefix:cas登錄域名 redirect-after-validation: true use-session: true server-name: http://localhost:8080
