springsecurity
Spring Security是一个功能强大且灵活的身份验证和授权框架,用于保护Java应用程序。它提供了一套全面的安全性功能,包括身份验证、授权、密码管理和会话管理等。
以下是Spring Security的用法示例:
1. 配置文件中添加Spring Security依赖:
```xml
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-security</artifactId>
</dependency>
```
2. 创建一个配置类来配置Spring Security:
```java
@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
http
.authorizeRequests()
.antMatchers("/public/**").permitAll()
.anyRequest().authenticated()
.and()
.formLogin()
.loginPage("/login")
.permitAll()
.and()
.logout()
.permitAll();
}
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth
.inMemoryAuthentication()
.withUser("user").password("{noop}password").roles("USER");
}
}
```
3. 创建一个登录页面:
```html
<!DOCTYPE html>
<html>
<head>
<title>Login Page</title>
</head>
<body>
<h2>Login Page</h2>
<form action="/login" method="post">
<label for="username">Username:</label>
<input type="text" id="username" name="username" required><br><br>
<label for="password">Password:</label>
<input type="password" id="password" name="password" required><br><br>
<input type="submit" value="Login">
</form>
</body>
</html>
```
4. 创建一个公共页面:
```html
<!DOCTYPE html>
<html>
<head>
<title>Public Page</title>
</head>
<body>
<h2>Public Page</h2>
<p>This page is accessible to all users.</p>
</body>
</html>
```
5. 创建一个受保护的页面:
```html
<!DOCTYPE html>
<html>
<head>
<title>Protected Page</title>
</head>
<body>
<h2>Protected Page</h2>
<p>This page is only accessible to authenticated users.</p>
</body>
</html>
```
