spring security 4 安全框架学习01

1、新建项目目录 security01-jc

2、在  security01-jc 新建pom.xml文件

pom.xml

3、在security01-jc 目录内新建 src/main/java 目录，在此目录下新建包(java 开发人员都知道也就是目录) 和类我的目录结构如下 ：

com.okttl.security

在此包下新建两个类SecurityConfig.java 和 SecurityWebApplicationInitializer.java

SecurityConfig.java  源码

 package com.okttl.security;

 import org.springframework.beans.factory.annotation.Autowired;
 import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
 import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
 import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;

 @EnableWebSecurity
 public class SecurityConfig extends WebSecurityConfigurerAdapter {

     @Autowired
     public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
         auth.inMemoryAuthentication().withUser("user").password("password").roles("USER");
     }
 }

SecurityWebApplicationInitializer.java 源码

 package com.okttl.security;

 import org.springframework.security.web.context.AbstractSecurityWebApplicationInitializer;

 public class SecurityWebApplicationInitializer extends
         AbstractSecurityWebApplicationInitializer {
     public SecurityWebApplicationInitializer(){
         super(SecurityConfig.class);
     }
 }

4、在security01-jc/src/main 目录内新建webapp目录。 在此目录内新建index.jsp 文件

index.jsp 代码：

     xmlns:c="http://java.sun.com/jsp/jstl/core" version="2.0">




               doctype-system="about:legacy-compat" />


     Hello Security





       This is secured!

         Hello

  

    

  

  

到此项目已经可以运行了。注意你的电脑上的jdk 要与 jdk.version 版本一致
