spring ModelAndView问题 - 添加“html”字首 [英] spring ModelAndView issue - adding "html" prefix

问题描述

我有春季启动应用程序：

I have spring boot app:

@RestController
@EnableAutoConfiguration
@Scope("prototype")
public class BillingController {

    @RequestMapping(value = "/testReport4_2", method = RequestMethod.GET)
    public ModelAndView helloReport(ModelMap modelMap, ModelAndView modelAndView) {
        JRDataSource datasource = new JRBeanCollectionDataSource(payordMng.getPayordGrpAll(), true);
    modelMap.put("datasource", datasource);
    modelMap.put("format", "pdf");
    modelAndView = new ModelAndView("Blank_A4_2", modelMap);
    return modelAndView;
}
...

配置：

@Configuration
public class MvcConfig extends WebMvcConfigurerAdapter {

    @Override
    public void addViewControllers(ViewControllerRegistry registry) {
        registry.addViewController("/home").setViewName("home");
        registry.addViewController("/hello").setViewName("hello");
        registry.addViewController("/login").setViewName("login");
    }

}

安全性：

@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    DataSource dataSource;

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
            .authorizeRequests()
                .antMatchers("/test.html", "/home", "/chrglsk", "/chrgall").permitAll()
                .anyRequest().authenticated()
                .and()
            .formLogin()
                .loginPage("/login")
                .permitAll()
                .and()
            .logout()
                .permitAll();

        http
        .csrf().disable();
    }

我的报告Blank_A4_2首先正常工作，并向我显示报告。
我这样访问它： http：// myserverIP / testReport4_2

My Report Blank_A4_2 firstly work fine, and it shows me Report. I access it so: http://myserverIP/testReport4_2

但如果我去任何静态页面，在我的项目中，例如
http：// myserverIP / test.html 然后如果我访问我的报告，
它将不显示任何内容，我将在下一个java控制台中看到：

But if I go to any static page, in my project, for example http://myserverIP/test.html and then if I visit back my report, it won't show anything and I will see in java console next:

class path resource [Blank_A4_2.html.jasper] cannot be opened because it does not exist

资源文件夹中的报告名称为Blank_A4_2.jasper，为什么spring boot添加
前缀html？

Му report name in resource folder is Blank_A4_2.jasper, why spring boot adds prefix "html" ?

推荐答案

我的问题类似于 JasperReportsViewResolver在一段时间后添加.html 。正如其中所建议的，我添加了
产生=application / pdf; charset = UTF-8
，如下所示：

My question is similar this one JasperReportsViewResolver add .html after some time. And as suggested in it, I added produces = "application/pdf;charset=UTF-8" like this:

@RequestMapping(value = "/testReport4_2", method = RequestMethod.GET, produces = "application/pdf;charset=UTF-8")

到控制器方法并解决了这个问题。

to the controller method and this problem solved.
