[alibaba/druid]springboot3.1.5 + druid-spring-boot-3-starter 启动异常

使用的druid-spring-boot-3-starter版本号为1.2.20

appliction.yml配置如下：

server:  
  port: 8080  
  servlet:  
    context-path: /  
  tomcat:  
    uri-encoding: UTF-8

项目采用了SpringSecurity安全配置

@Configuration
public class SecurityConfig
{
    @Bean
    public SecurityFilterChain filterChain(HttpSecurity httpSecurity) throws Exception {
        return httpSecurity
                .authorizeHttpRequests(authorizeRequests -> authorizeRequests
                        .requestMatchers(HttpMethod.GET, "/", "/*.html", "/**.html", "/**.css", "/**.js").permitAll()
                        .requestMatchers("/druid/**").permitAll()
                        .anyRequest().authenticated())
                .build();
    }
}

启动不了，抛出如下异常：

异常信息中，重点如下：

This is because there is more than one mappable servlet in your servlet context: {org.springframework.web.servlet.DispatcherServlet=[/], com.alibaba.druid.support.jakarta.StatViewServlet=[/druid/*]}.

但是如果去掉appliction.yml文件中的statViewServlet配置，则可以启动, 也即application.yml:

```yml

    context-path: /

搜一下CVE-2023-22602漏洞，使用SpringSecurity新版本需要改写代码的，简单一点是改成这样：

        return httpSecurity
                 .authorizeHttpRequests(authorizeRequests -> authorizeRequests
                         .requestMatchers(AntPathRequestMatcher.antMatcher(HttpMethod.GET, "/")).permitAll()
                         .requestMatchers(AntPathRequestMatcher.antMatcher(HttpMethod.GET, "/*.html")).permitAll()
                         .requestMatchers(AntPathRequestMatcher.antMatcher(HttpMethod.GET, "/**.html")).permitAll()
                         .requestMatchers(AntPathRequestMatcher.antMatcher(HttpMethod.GET, "/**.css")).permitAll()
                         .requestMatchers(AntPathRequestMatcher.antMatcher(HttpMethod.GET, "/**.js")).permitAll()
                         .requestMatchers(AntPathRequestMatcher.antMatcher("/druid/**")).permitAll()
                         .anyRequest().authenticated())
                 .build();

更严谨的做法是改成MvcRequestMatcher

按照你写的代码修改，运行Application，同样抛出之前的错误，异常信息中，重点如下： This is because there is more than one mappable servlet in your servlet context: {org.springframework.web.servlet.DispatcherServlet=[/], com.alibaba.druid.support.jakarta.StatViewServlet=[/druid/*]}.

我的能正常启动，我用的springboot3.1.5+ spring security config6.1.5 + spring security web6.1.5，改写之前应用启动时和你一样的提示，按照提示修改了就启动成功了

zrlw

这个问题和druid没什么关系，你还是去spring security社区找找吧，看看升级之后代码需要怎么改写。

zrlw

我用eclipse + jdk17对当前master分支代码重新做了一下验证，在druid-spring-boot-3-starter模块的测试package里加上你的这个SecurityConfig，确认不改写就抛异常，改写了就ok。当然现在的master分支的core模块在jdk17上编译有错误，还要改pom和代码，主要需要修改的内容如下：

core模块pom干掉hive-jdbc依赖，这个东西依赖tools.jar，jdk17下没有了，扫了代码和测试类都没有用到它，应该只是个残留垃圾。
替换@Resource注解，jdk17没有这个注解，需要替换成@Autowired和@Qualifier，改了StatAnnotationBeanPostProcessor.java。

在druid-spring-boot-3-starter测试package填加SecurityConfig，修改pom添加SecurityConfig需要的spring-security：

    <dependency>
        <groupId>org.springframework.security</groupId>
        <artifactId>spring-security-config</artifactId>
        <scope>test</scope>
    </dependency>

    <dependency>
        <groupId>org.springframework.security</groupId>
        <artifactId>spring-security-web</artifactId>
        <scope>test</scope>
    </dependency>

父pom的springboo3版本改成3.1.5，以验证你碰到的问题。
```
<springboot3.version>3.1.5</springboot3.version>
```
确认eclipse配置Content Types - Text里的java Properties File缺省编码配的是UTF-8，这个配置坑了我一下，eclipse这个选项默认是ISO-8859-1，内容有汉字的properties文件并不会被加载。为了避免出现此类问题，大多数开源软件要求默认的配置文件必须使用英文注释，但是druid配置文件一眼看去全是汉字，可能druid的定位只是面向国内用户吧。因为druid的pom加了checkstyle校验，但有些测试类并不符合要求，我懒得改了，用jdk17执行clean package -B重新打包全部模块时skip排除掉了单元测试，所有模块全部打包成功后再单独mvn test构建druid-spring-boot-3-starter的测试类，以便测试DemoApplication。测试jre我直接用了eclipse自带的jdk17，debug确认应用先执行了DruidStatViewServletConfiguration，证明application.properties的statViewServlet启用配置生效了，然后执行到了SecurityConfig，如果用你写的方式，就会抛异常：停掉应用，把SecurityConfig改写成下面这个样子后，重新debug确认SecurityConfig执行成功，应用也随之启动成功：

zrlw

to @zrlw : 按照你的步骤，能显示druid的登陆页面，但是输入正确的用户名和密码登陆不上去，Http Response返回403. application.yml文件中也删除了所有的中文字符，采用UTF-8格式。

zouzg7829

配置spring-security默认是开启csrf，403是被CsrfFilter阻断了，druid是restful，post请求都不带csrfToken，目前druid并没有提供这些功能，用security意味着你自己要定制。如果你不担心跨站攻击，可以直接禁用csrf了事，否则你就要写很多代码了，如果不熟悉相关内容，应该还有很多问号或者惊叹号在前面等着你。

zrlw

AbstractRequestMatcherRegistry.java:208行的原因，idea中下载源码，debug一下就知道了，所有pattern都要显示声明为antPattern或者mvcPattern
