java - Spring Boot - 不允许使用 Post 方法，但 GET 有效

Question

我的 spring boot mysql 项目有问题， Controller 类只为 METHOD GET(get all) 查找，但我似乎无法发布并得到错误 405:方法“POST”不允许

这是我的 Controller 类:

 package com.example.demo.controller;


import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;

import com.example.demo.Blog;
import com.example.demo.repository.BlogRespository;

import java.util.List;
import java.util.Map;

@RestController
public class BlogController {

    @Autowired
    BlogRespository blogRespository;

    @GetMapping("/blog")
    public List<Blog> index(){
        return blogRespository.findAll();
    }

    @GetMapping("/blog/{id}")
    public Blog show(@PathVariable String id){
        int blogId = Integer.parseInt(id);
        return blogRespository.findById(blogId)
                 .orElseThrow(() -> new IllegalArgumentException(
                 "The requested resultId [" + id +
                 "] does not exist."));
    }

    @PostMapping("/blog/search")
    public List<Blog> search(@RequestBody Map<String, String> body){
        String searchTerm = body.get("text");
        return blogRespository.findByTitleContainingOrContentContaining(searchTerm, searchTerm);
    }

    @PostMapping("/blog")
    public Blog create(@RequestBody Map<String, String> body){
        String title = body.get("title");
        String content = body.get("content");
        return blogRespository.save(new Blog(title, content));
    }

    @PutMapping("/blog/{id}")
    public Blog update(@PathVariable String id, @RequestBody Map<String, String> body){
        int blogId = Integer.parseInt(id);
        // getting blog
        Blog blog = blogRespository.findById(blogId)
             .orElseThrow(() -> new IllegalArgumentException(
             "The requested resultId [" + id +
             "] does not exist."));
        blog.setTitle(body.get("title"));
        blog.setContent(body.get("content"));
        return blogRespository.save(blog);
    }


    @DeleteMapping("blog/{id}")
    public boolean delete(@PathVariable String id){
        int blogId = Integer.parseInt(id);
        blogRespository.delete(blogId);
        return true;
    }


}

如果你需要的话，这是我的存储库类

package com.example.demo.repository;

import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.stereotype.Repository;

import com.example.demo.Blog;

import java.util.List;

@Repository
public interface BlogRespository extends JpaRepository<Blog, Integer> {

    // custom query to search to blog post by title or content
    List<Blog> findByTitleContainingOrContentContaining(String text, String textAgain);

}

我正在尝试使用 SoapUI 发送 POST 请求，但似乎找不到解决方案，非常感谢

如果您配置或启用了 csrf，则不允许发布方法那么您需要在发布表单或数据时提供有效的 csrf

为此检查你的 spring 安全配置例如

    @Configuration
    @EnableWebSecurity
    @ComponentScan(basePackageClasses = CustomUserDetailsService.class)
    public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
    .....

RequestMatcher csrfRequestMatcher = new RequestMatcher() {
        // Enabled CSFR protection on the following urls:
        //@formatter:off
        private AntPathRequestMatcher[] requestMatchers = 
            {
                new AntPathRequestMatcher("/**/verify"),
                        new AntPathRequestMatcher("/**/login*")
            };
        //@formatter:off

        @Override
        public boolean matches(final HttpServletRequest request) {
            // If the request match one url the CSFR protection will be enabled
            for (final AntPathRequestMatcher rm : requestMatchers) {
                if (rm.matches(request)) {
                    System.out.println();
                    /* return true; */
                }
            }
            return false;
        } // method matches
    };
@Override
    protected void configure(final HttpSecurity http) throws Exception {
        //@formatter:off

        http.headers().frameOptions().sameOrigin()
        .and()
        .authorizeRequests()
        .antMatchers("/","/css/**", "/static/**", "/view/**", "**/error/**").permitAll()
        .anyRequest().authenticated()
        .and()
        .formLogin().loginPage("/mvc/login").permitAll() 
        .authenticationDetailsSource(authenticationDetailsSource())
        .successHandler(authenticationSuccessHandler)
        .usernameParameter("username").passwordParameter("password")
        .and()
        .logout().permitAll()
        .logoutRequestMatcher(new AntPathRequestMatcher("/logout"))
        .addLogoutHandler(customLogoutHandler)
        .logoutSuccessHandler(customLogoutSuccessHandler)
        .logoutSuccessUrl("/login?logout")
        .and()
        .exceptionHandling()
        .accessDeniedPage("/403")
                .and()
                .csrf()/* .requireCsrfProtectionMatcher(csrfRequestMatcher) */
        .ignoringAntMatchers("/crud/**","/view/**")
    ;
        // @formatter:off


    }

谢谢
