修改 pom 文件, 使其支持 jdk1.8

<plugin.compiler.version>2.0.2</plugin.compiler.version>
 
 
<!-- 设置 java sdk 版本 -->
<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>${plugin.compiler.version}</version>
    <configuration>
        <source>${system.java.version}</source>
        <target>${system.java.version}</target>
    </configuration>
</plugin>
  • 修改 Security 配置文件使其支持跨域(使用 SpringBoot 内置跨域(不友好))
@Override
protected void configure(HttpSecurity http) throws Exception {
    // 允许直接访问/路径
    http.authorizeRequests().antMatchers("/").permitAll()
            // 使其支持跨域
            .requestMatchers(CorsUtils :: isPreFlightRequest).permitAll()
            // 其他路径需要授权访问
            .anyRequest().authenticated()
            // 指定登录页面
            .and().formLogin().loginPage("/user/login")
            // 登录成功后的默认路径
            .defaultSuccessUrl("/").permitAll()
            // 退出登录后的默认路径
            .and().logout().logoutSuccessUrl("/user/login").permitAll();
}

使用html 页面进行跨域, 即每次请求将后台的跨域字符串写到前端页面隐藏域, 每次请求的时候在携带这两个隐藏域值访问后台请求(不推荐)

  • 在 config 目录中创建 CorsConfig 跨域配置文件(用户自定义实现跨域)

spring Security 3默认关闭csrf,Spring Security 4默认启动了csrf. 加上
.csrf().disable()即可关闭csrf

修改App 应用入口文件配置扫描路径
package com.edurt;
 
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;
 
/**
 * Hello world!
 */
@SpringBootApplication
// 设置扫描路径
@ComponentScan(value = "com.edurt")
public class App {
 
    public static void main(String[] args) {
        SpringApplication.run(App.class, args);
    }
 
}
